Stainless Steel 422 Fasteners are martensitic, hardenable fasteners primarily made of iron, with about 12% chromium, 1% molybdenum, and trace amounts of tungsten and vanadium. These components give the fasteners remarkable strength, hardness, and resistance to oxidation. When heat-treated, SS 422 achieves a tensile strength ranging from 760 to 1050 MPa and a yield strength between 450 and 850 MPa, depending on the tempering process. This alloy maintains its mechanical integrity at high temperatures, up to 650°C (1200°F), providing excellent resistance to creep and fatigue. These fasteners are perfect for structural and mechanical applications that require durability, thermal stability, and outstanding wear resistance.
