Stainless Steel 422 Stud Bolts are made from a martensitic stainless steel alloy containing around 12% chromium, along with small amounts of nickel, molybdenum, and vanadium. This composition allows the material to be heat treated for high tensile and yield strength. Mechanically, 422 Stud Bolts provide excellent hardness, good fatigue resistance, and strong creep resistance at elevated temperatures. They also offer moderate corrosion and oxidation resistance, making them suitable for high-stress and high-temperature service conditions.
