Stainless Steel 440B is a high-carbon martensitic stainless steel containing elevated chromium levels for enhanced corrosion resistance. It offers superior hardness and tensile strength, especially after heat treatment. Known for its excellent wear resistance and ability to maintain a sharp edge, SS 440B provides good toughness and moderate corrosion protection in mild environments. The alloy responds well to hardening processes such as quenching and tempering, allowing it to achieve high mechanical strength and stability. These characteristics make it ideal for demanding applications requiring durability, cutting performance, and resistance to abrasion.
