Description: Type430 Stainless Steelis a low carbon ferritic stainless steel which, in mildly corrosive environments or atmospheric exposures, has corrosion resistance approaching that of some nickel-bearing stainless steels. This alloy is oxidation resistant at elevated temperatures. Type 430 is ductile, does not work harden readily, and can be formed using a variety of roll forming or mild stretch bending operations as well as the more common drawing and bending processes. Type 430 is ferromagnetic. Product Forms: Stainless Steel Sheet, Stainless Steel Coil, Stainless Steel CoilStrip, Stainless Steel Pipe, Stainless Steel Bar, Stainless Steel Wire. Typical Applications: Sinks, sink rims, appliance trim, counter tops, dish washers, range hoods, flatware, architectural uses, roofing, siding and restaurant equipment.

If the annealing temperature does not exceed 1450°F (790°C), an air cool may be substituted for the furnace cool when annealing thin sections. Forming: Type 430 is readily drawn and formed. Its drawing characteristics are similar to those of low-carbon steel, although it is stronger in the annealed condition and will require stronger tooling and increased power. Welding: Type 430 is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid brittle weld fractures during fabrication. When a weld filler is needed, AWS E/ER 308L and 430 are most often specified. Corrosion: This alloy is resistant to attack in a wide variety of corrosive media including nitric acid, and many organic acids.
