Stainless Steel Flat Rolled Coil

Rolled Steel Products offers the following types of Stainless Steel Flat Rolled Coil

Austenitic stainless steels contain chromium and nickel (300 Series types) as well as chromium, nickel and manganese (200 Series types). Most stainless slit coils can be hardened by cold-working but not by heat treatment. All are non-magnetic in the annealed condition as well, though some may become slightly magnetic by cold-working. Stainless steel slit coils also have excellent corrosion resistance and unusually good formability. The stainless slit coils increase in strength as a result of cold work. With a nominal composition of 18% chromium and 8% nickel, Type 304 (sometimes referred to as 18-8 stainless) is the most widely used alloy in this group.

Ferritic stainless slit coils are straight-chromium 400 Series types that cannot be hardened by heat treatment and only moderately hardened by cold-working. They are magnetic with good ductility and resistant to corrosion and oxidation. Type 430 is the general-purpose stainless steel of this group. Type 430 is by far the most popular of all straight chromium stainless steels. It is the general purpose alloy of the ferritic class. This type contains approximately 17 percent chromium and is often referred as 17 chrome stainless. The higher chromium content imparts improved resistance of Type 430 is slightly less than carbon steel, but its thermal conductivity is one half that of carbon steel.

Martensitic stainless slit coils are straight-chromium 400 Series types that can be hardened by heat treatment. They are magnetic and, in mild environments, resistant to corrosion. They have fairly good ductility, and some can be heat-treated to tensile strengths exceeding 200,000 psi (1379 MPa). Type 410 is the general-purpose alloy of this group.

Properties of Stainless Steel
High oxidation-resistance in air at ambient temperature is normally achieved with additions of a minimum of 13% (by weight) chromium, and up to 26% is used for harsh environments. The chromium forms a passivation layer of chromium(III) oxide (Cr2O3) when exposed to oxygen. The layer is too thin to be visible, and the metal remains lustrous. The layer is impervious to water and air, protecting the metal beneath. Also, this layer quickly reforms when the surface is scratched. This phenomenon is called passivation and is seen in other metals, such as aluminum and titanium. Corrosion-resistance can be adversely affected if the component is used in a non-oxygenated environment, a typical example being underwater keel bolts buried in timber.

When stainless steel parts such as nuts and bolts are forced together, the oxide layer can be scraped off, causing the parts to weld together. When disassembled, the welded material may be torn and pitted, an effect known as galling. This destructive galling can be best avoided by the use of dissimilar materials for the parts forced together, for example bronze and stainless steel, or even different types of stainless steels (martensitic against austenitic), when metal-to-metal wear is a concern, but two different alloys electrically linked in humid environment work as pile and corrode faster. Nitronic alloys reduce the tendency to gall through selective alloying with manganese and nitrogen. Additionally, threaded joints may be lubricated to prevent galling.

Similarly to steel, stainless steel is not a very good conductor of electricity, with about a few percent of the electrical conductivity of copper.

Ferritic and Martensitic stainless steels are magnetic. Austenitic stainless steels are non-magnetic.

STAINLESS STEEL SLITTING

At Rolled Steel Products, our job is more than slitting stainless steel and shipping stainless steel coils, our job is to meet all of your stainless steel requirements from order entry to delivery, and everything in between.

If you require stainless strip, we have several possible options to choose from. Our Loopco and Stamco precision slitters can slit up to 52 inches wide, run approximately 1000 FPM, slit up to 30 cuts at a time, and keep within .002 to .003 width tolerance. Rolled Steel Products carries a wide range of finishes and types in both 300 and 400 series stainless steel sheet and coil.

304 STAINLESS STEEL
Type 304 (UNS S30400) is the most widely used of the austenitic chromium-nickel stainless steels.Its carbon content is lower and its corrosion resistance somewhat higher than Type 302. In the annealed condition, Type 304 is essentially nonmagnetic and becomes slightly magnetic when cold worked. In the lower carbon Type 304L material, carbide precipitation as a result of welding will be minimized, resulting in less susceptibility to intergranular corrosion.

430 STAINLESS STEEL
Type 430 is ductile, has good forming characteristic and is readily fabricated by such operations as bending, pressing, drawing and heading. Its tendency to work harden is much less than that of the nickel-bearing 300 series stainless steel. Type 430 does not have as good corrosion resisting properties as the chromium nickel steels. However, it is suitable for interior architectural and decorative household appliances trim as well as automotive body molding. Cold rolled Type 430 has an attractive bright finish which can be maintained with reasonable care and periodic cleaning. Type 430 is by far the most popular of all straight chromium stainless steels. It is the general purpose alloy of the ferritic class. This type contains approximately 17 percent chromium and is often referred as 17 chrome stainless. The higher chromium content imparts improved resistance of Type 430 is slightly less than carbon steel, but its thermal conductivity is one half that of carbon steel. Chromium stainless steel is magnetic.

 

 

The Lowdown Behind 430 Stainless Steel

If you live in California, steel is one of the key products the state is well known for. According to statistics, close to 69% of this metal is recycled annually. This is more than the paper, plastic, aluminum, and glass combined. The first known commercial application of steel was in 1883 when skyscrapers were just starting to go up. While its uses are exhaustive and extensive, the practice of recycling is strictly adhered to in order to reduce its environmental impact.

Steel is an alloy, made up of mostly iron but with a carbon content of 0.2% to 2.1% by weight. Though carbon is a common component in its production, there are other alloy materials such as tungsten, chromium, and manganese to be found. The proportions and forms, in which these different elements are used, affect the outcome of the steel produced. Increasing the carbon content, for instance, will result in a product that offers increased strength. This is extremely important when making steel for different purposes. A beverage can's requirements will be different from what is needed to make railway tracks.

Steel is assessed based on a number of properties. These include tensile strength, ductility, malleability, durability, conductivity, luster, and rust resistance.

Now if you think there is just one type, you are wrong. There are actually different grades of the product. There is mild steel that is a type of carbon steel. 430 stainless steel and 304 are the two others most commonly used. While they both have their similarities, they also have enough differences that keep them unique.

When it comes to features, here is where they differ. In terms of 430 steel, the metal has magnetic properties, while 304 steel does not have any. Also, 430 is a less expensive grade and can be somewhat difficult to form and weld. Type 304, on the other hand, is easier to create and form shapes with.

In the realm of applications, 430 are preferred in the production of automotive trim, the insides of clothes dryers, and dishwashers. Manufacturers use 304 steel for creating kitchen sinks, countertops, food processing equipment, and other items regularly exposed to corrosive environments.

Regarding the composition, 430 stainless steel is made up of 17% chromium and 0.12% carbon. 304 stainless steel contains 18% chromium and 0.08% carbon.

California steel has been used in most anything, from manufacturing agricultural implements to building bridges. Other things you come across include railway tracks, cars, engines, and airplanes. In fact, you will be hard pressed to find something that doesn't contain an element of this highly versatile metal. Its unique properties allow it to be used in a variety of ways that make it indispensable to everyday living. Over the years, production has increased to its current levels of close to 1300 million tons a year. Whether it's a fruit knife, an electric razor, a hair pin, or an entire building, there is a little bit of this marvelous metal in everything.

Steel is, without a doubt, one of the most essential and most significant substances humans have ever worked with. It has fueled the growth of civilizations, spurred the rise of economies, and is a vital part of every individual's life. For many homes, like in California, steel framing provides better strength and durability. Houses with metal frames are also expected to stand for generations unlike those made with wood.

This substance can be found everywhere even if the average person may not notice – in office buildings, in homes, public parks, and grocery stores; in all probability this can even be one of the first things a person can interact with when he or she wakes up in the morning. This just goes to show how popular and useful this substance is.  

A Special Kind of Metal

There are many different types of metal alloy used for different purposes; however, one type is especially popular. This is 430 stainless steel, a type of metal alloy usually found in homes. It is also the most commonly used than any other type of steel. This kind is non-heat treatable, is ductile, has good formability, and is easily formed by processes such as bending, drawing, pressing, and heading. These properties, along with its ability to have a bright attractive finish, are the reasons why this substance is a sought after material for products like automotive trims, decorative household appliances, and interior architectural finishing.

Steel and Today's Economy

The popularity of 430 stainless steel is only one indicator of how much this material, or more accurately, substances like California steel, is a very popular product around the world. Even with the world's economies still reeling from the recent economic recession, the demand for this material is still very high and isn't seen to slow down. The demand slowed down a little during the economic recession, but picked up again within a few years. Many economists and industry experts attribute this to countries like China, India, and other rising economies with growing demand for steel. Those looking for a reliable supplier of this type of prized material need not look any further: we have the quality products you need.
 

California Steel Industries at Your Service

Steel is one of the most common construction materials. It has several types and each has specific properties. Choosing the right type of steel is very important. This is why you need proper knowledge or consult a professional to get the most appropriate materials.

The California steel industry helps small and big businesses with infrastructure facilities construction. If you want excellent steel construction services, there are companies providing prefabricated metal building materials throughout United States including Arizona, Texas, and California. They can also help you find the right tools for your projects.

Steel types have differing properties and composition. This is why you need to know which metal is best for your project. A slight difference in hardness and texture can easily affect the appearance and function of a particular construction.

So what is stainless steel?

Stainless steel is an iron-based metal. It contains 10 percent chromium and alloy metals. This metal does not stain, rust, nor corrode as easily as ordinary steel. They also differ from carbon steel when it comes to the amount of chromium present. Unprotected carbon rusts easily when exposed to air or moisture. The iron oxide film or rust can accelerate corrosion by forming more iron oxide.

Stainless steel contains enough chromium to form a passive film of chromium oxide. This prevents corrosion and blocks iron oxide from spreading into the metal’s surface.

Now what is type 430 stainless steel?

This type of steel is a low carbon, "ferretic" stainless metal. Specialists consider it as pure iron for having ferromagnetic properties. These properties and mechanism of substances enable it to become a permanent magnet. This type can also resist corrosion and oxidation.

Type 430 stainless steel is also flexible. You can easily put in under a machine compared to other types. This is the why it is the most preferred material for construction projects. 

430 Stainless Steel: Tough Enough to Withstand the Test of Time

Look around you and you will find steel. It is one of the world's most widely used metals. Without it, the industrial revolution would have never happened. This is why it is a material that continues to be of great importance. While people tend to gloss over its significance, it continues to withstand the test of time and will remain important for future generations to come.

In states like New York and California, steel is used in many different ways. You will find it used primarily for industrial purposes. Walk down the streets of every modern metropolis and you will find this metal all around you. The reason New York got its nickname "The Empire State" was because of the number of buildings going up during the early beginnings of the 20th century. Great steel girders were being hoisted into the air to create the impressive skyline Manhattan is well known for.

There was not much experimentation with steel in its early forms; however, the early 1800s brought a period of great change. A new variant of steel was discovered. This came to be known as stainless steel. As with any new form, prototypes did not turn out too well. They were brittle for everyday use. It was only in the 1900s that the steel we know today was perfected.

Two gentlemen were credited for its perfection, Elwood Haynes and Harry Brearley. American stainless steel production began in Pennsylvania in 1913. In the western United States, specifically California, steel production was also starting to get its bearings.

Today, you will find steel in various forms. 430 stainless steel is the one most commonly used. It is of the ferrite class and contains between 10.5-25% chromium. There is also a minimal amount of nickel to be found. For these reasons, it is an excellent steel variant that can be used in many different fields.

In case you are wondering what products and appliances use 430 stainless steel, just take a look at your car. Most automotive trims and molding are made from this. Simple, everyday objects like zippers and fasteners are also formed from this material. Another place to find this steel is inside a modern, professional kitchen. Because commercial cooking adheres to strict standards, fixtures and appliances are usually made from this highly versatile metal.

The Place of 430 Stainless Steel in Society

Steel is one of the most popularly used substances on the planet. It is one of the industrial foundations upon which modern society is built. People have been making tools and devices to help make their lives easier ever since man first discovered metals like bronze, copper, and iron. It was steel that ushered mankind into the Industrial Age and urbanization. The discovery and different applications of steel in various industries helped bring about the Industrial Revolution, which took place from the 18th to 19 th century. The invention of things such as steam engines, railways, machine tools, and the like could not have been possible if not for steel. Today, steel is very much an important part of the different industries in the world, as sales of items like California steel products continue to rise.  

What is Steel?

Steel is a metal alloy that contains iron and a small amount of carbon or other different elements such as manganese, vanadium, and tungsten. The different combinations of raw materials used in steel production, as well as the various processes used to make them, gives us the many different types of steel. For instance, 430 stainless steel is composed of iron, carbon, chromium, manganese, nickel, silicon, sulfur and phosphorus. Meanwhile, 440C stainless steel is composed of just carbon, chromium, and iron.

Steel Forming Processes

With this in mind, the processes of making the different types of California steel products also differ. When a steel alloy is created, it can be worked into various kinds of steel products. Steel alloy can be formed into their desired shape by metalworking processes like cold rolling and hot rolling. Cold rolling is when a piece of the raw metal stock is passed through a pair of rolls. This can produce different-shaped steel products such as steel plates or bars, depending on the rolls used.
Hot rolling relies on the same concept of passing metal stock through rollers. The difference between hot and cold rolling is in the metal stock’s temperature as it is put through the rolls. When the metal stock is rolled below its recrystallization temperature, the process is called cold rolling and the resulting products are called cold-rolled steel. On the other hand when the metal stock’s temperature is above its recrystallization point as it goes through the rollers, the process is called hot rolling and the finished product is called hot-rolled steel.

Modern Steel

Today, products like 430 stainless steel and cold-rolled California steel products are some of the most sought after materials in the various fields of industry throughout the world. According to the World Steel Association, in 2010 alone the countries of the world combined to produce 1,413.6 million metric tons of steel. China is the biggest steel producer the world, accounting for 44.3 percent. The economic recessions of the last couple of years didn’t even make a dent in the steel industry. Production slowed from 2008-2009, but picked up again going into 2010. With emerging countries like China seeking steel to further improve its economic growth, the steel industry has a bright future ahead of it.

430 Stainless Steel: The Steel of Choice in Homes and Industries

Steel is the one of the most widely used metals in the world. It played an integral part in the industrial revolution and continues to be of great importance to our world today. Many people overlook the material and regard it as purely a commodity. Most do not realize its dated history and importance to our society.

In highly urbanized areas from New York to California, steel is an important material that is used in different ways. For the most part, it is used for industrial purposes. Take a walk down the streets of any modern metropolis and you will come to learn just how important the material is. If you don't already know, steel is the metal used as the foundation for most buildings.

The metal served this purpose from the time of its discovery until the early 1800s. It was during this century that experimentation with a new variant started. This was known as stainless steel. The first few prototypes didn't turn out very well. They were too brittle for practical use. Experiments with the material continued throughout the century, but the steel we know today didn't come until the early 1900s.

Elwood Haynes and Harry Brearley are the two people credited for the discovery of the product we use. The production of American stainless steel began in Pennsylvania in 1913.In the west coast, specifically California, steel production was also starting to pick up.

The product comes in many different forms, but one of the most common is 430 stainless steel. It is a variant that belongs to the ferritic class and usually contains between 10.5-25% chromium and little to no nickel. This makes it ideal for use in many different fields.

Some of the more common products and appliances made with 430 stainless steel include automotive trims and molding and interior architectural trim and paneling. It is also used for simple things like zippers and fasteners. In addition, it is also widely recognized for its application in kitchen trim and equipment. If you've ever stepped foot in a modern, industrial kitchen; chances are that most of the fixtures and appliances you see are made of this type of stainless steel. It is really one of the most versatile kinds in the world.

Rolled Steel Products is equipped with an on-site Cold Reduction Mill capable of delivering strips of steel with tolerances of +/- .0005, the closest tolerance in the industry. With our Cold Reduction Mill, our highly skilled operators are able to closely monitor the entire milling process from raw steel to finish strip. This allows for the highest level of quality control of our cold reduced products, thus allowing for better consistancy and efficiency throughout the entire strip. We provide carbon, stainless and aluminum steel in any of the commmercially available tempers and finishes.

Cold Rolling is a process by which the sheet metal or strip stock is introduced between rollers and then compressed and squeezed. The amount of pressure introduced determines the hardness and other material properties of the finished product. Our Waterbury Farrel® 2-Hi/4-Hi Combination Mills may be converted by the removal or insertion of work rolls. This permits greater versatility of rolling capabilities on the same mill. When production requirements are relatively small, a single mill of this type can be used for breakdown, rundown and finish rolling.

The advantages of cold rolling steel is the capability to keep the tolerances very close, as well as tightening up the grain structure of the steel. The finished tolerances on hot rolled steel are looser than on cold rolled. With the advantage of our extremely close tolerances we are able to provide elite industry professionals with greater consistancy, allowing faster stamping and fabrication efficiencies.

When it comes to delivering your product to you, Rolled Steel Products has their own fleet of trucks for your convenience and quick on time delivery.

 

 

 

 

February 2012: Industry Update

From Rolled Steel Products perspective it appears that the steel market is at a plateau, whereby we could see prices stabilizing or even possibly falling a bit. For the past two months or so domestic prices have been increasing fairly significantly, while the foreign prices have increased only slightly. Lead-times domestically from mill sources have been shrinking or staying stable across the nation. Service Centers are still keeping inventories at a minimal with many steel buyers still having great concern about supply and demand. The domestic mills (and steel buyers) are concerned about two areas which will be impacting the domestic market-increased capacity and imports. We possibly could see a rush of more imported steel which would certainly drive the prices down domestically. It is our goal to watch both markets carefully and keep our inventory at appropriate levels while keeping a continuity in supply for our ongoing existing customers.
