Stainless steel 410/420, also known as UNS S41000 and UNS S42000, is considered a basic martensitic stainless steel. Comprised of 11.5% to 13.5% chromium and iron, along with trace amounts of other elements including carbon, manganese, phosphorus, silicon, and sulfur. After heat treatment, Stainless Steel 410 exhibits high mechanical properties, it is magnetic in both hardened and annealed conditions. Upon specification, Stainless Steel 410 can be delivered in a hardened, yet still machinable state for uses where moderate corrosion resistance and high strength are required. Stainless Steel 410 reaches maximum corrosion resistance when hardened, tempered and polished. It can be welded using most common welding methods, hot worked between 2000° F and 2200° F, as well as, cold formed and annealed. Because of all of these traits it is widely considered the “general purpose grade” of stainless steel.
