430 Stainless Steel
UNS S43000
Description
430 stainless steel is a low-carbon plain chromium ferritic stainless steel, which combines good corrosion resistance with good formability and ductility. In the annealed condition, 430 stainless steel is ductile, does not harden excessively during cold work and can be formed using a large variety of roll forming or mild stretch-bending operations, as well as the more common drawing and bending processes. 430 stainless steel also has excellent resistance to nitric attack, which makes it well suited to use in chemical applications.
