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.
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.
