Stainless Steel 440C Coils are made from high-carbon martensitic stainless steel, featuring around 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese, silicon, molybdenum, and nickel. This unique blend gives the alloy its remarkable hardness, excellent wear resistance, and decent corrosion resistance. On a mechanical level, SS 440C boasts high tensile strength, impressive edge retention, and outstanding surface hardness after heat treatment. These characteristics make it one of the hardest stainless steels available, perfect for applications where strength and durability are crucial.
