304 STAINLESS STEEL
Type 304 (UNS S 30400) is the most widely used of the austeniticchromium-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.
