The composition of Stainless Steel 422 Stud Bolts primarily includes iron, chromium (12–14%), molybdenum, nickel, and a higher carbon content than standard stainless grades. This martensitic alloy delivers impressive tensile strength, remarkable hardness, and resistance to scaling at high temperatures. Mechanical properties showcase a tensile strength range of 620–850 MPa, a yield strength of about 450 MPa, and hardness reaching up to 45 HRC after heat treatment. Their structure is designed to ensure toughness, creep resistance, and durability even under thermal cycling. Additionally, Stainless Steel 422 offers good corrosion resistance in mild environments, making these stud bolts ideal for critical and high-performance applications.
