Chanchai Stainless, a trusted supplier in Bangkok, Thailand, provides Stainless Steel 422 Bolts engineered for high strength, toughness, and heat resistance. As a martensitic stainless steel, grade 422 is built for high-temperature service, offering superior creep resistance and oxidation stability up to 650°C. These bolts can be heat treated to achieve excellent mechanical strength while retaining toughness. Stainless Steel 422 Bolts are widely used in aerospace, power generation, and industrial machinery. Chanchai Stainless ensures precision manufacturing, making 422 bolts a reliable fastening choice for environments requiring strength, heat resistance, and long-term durability.
Stainless Steel 422 bolts contain chromium (12-14%), molybdenum (~1%), tungsten, vanadium, and higher carbon (~0.2-0.3%). The alloy’s martensitic structure offers excellent strength and creep resistance. Mechanical properties include a tensile strength of up to 760 MPa and a yield strength around 450 MPa, with hardness levels achieved through heat treatment. The oxidation resistance is reliable up to 650°C, with good toughness and wear resistance. Stainless Steel 422 combines corrosion resistance with high mechanical performance, making it ideal for heavy-duty fasteners in challenging environments.
