What is Stainless Steel 440b Washers?
Stainless Steel 440B washers are crafted from high-carbon martensitic stainless steel, typically composed of 0.60–0.75% carbon, 16–18% chromium, and trace amounts of manganese, silicon, and molybdenum. This composition provides excellent hardness, wear resistance, and moderate corrosion resistance. Mechanically, 440B washers exhibit a tensile strength of approximately 700–850 MPa, hardness up to 57 HRC after heat treatment, and good fatigue resistance. These properties make them ideal for precision applications, including automotive, machinery, and industrial equipment, where durability, strength, and reliability under high stress and wear conditions are essential.
