Stainless Steel 440B Sheets and Plates are high-carbon, high-chromium stainless steel products that stand out for their remarkable hardness, strength, and excellent wear resistance. As a favored grade in the 440 stainless family, 440B strikes a balance by offering better toughness than 440C while still delivering superior hardness compared to 440A, making it perfect for demanding applications. These sheets and plates find their place in industries that need components capable of withstanding abrasion, high stress, and moderate corrosion. Their ability to maintain mechanical integrity in tough operating conditions makes them a go-to choice for manufacturing tools, blades, industrial machinery parts, and precision instruments where durability and performance are key.
Stainless Steel 440B is made up of high carbon, 16–18% chromium, along with small amounts of manganese, silicon, and molybdenum. The elevated carbon content significantly boosts hardness and tensile strength after heat treatment. It boasts a tensile strength range of 750–1100 MPa and excellent edge-retention properties. 440B also shows good wear resistance and moderate corrosion resistance, particularly in hardened and tempered states. Its mechanical characteristics make it ideal for precision components that require high durability, superior strength, and reliable performance in abrasive and mechanically stressful environments.
