Akor Stainless is a top-notch manufacturer and supplier based in Abuja, Nigeria, specializing in high-strength Stainless Steel 422 Bolts that are designed to excel in high-temperature and high-stress settings. These martensitic stainless steel bolts are celebrated for their remarkable heat resistance, hardness, and ability to fend off corrosion. Crafted with precision and a commitment to international standards, Akor Stainless guarantees dimensional accuracy and consistent quality. SS 422 Bolts are perfect for critical industrial applications where durability, oxidation resistance, and mechanical stability are a must. They’re commonly found in power generation, aerospace, petrochemical, and turbine systems that operate under extreme thermal and pressure conditions.
Stainless Steel 422 Bolts are made up of 11–13% chromium, 1–1.5% molybdenum, 0.2–0.35% carbon, along with trace amounts of tungsten and vanadium. This martensitic alloy boasts a tensile strength ranging from 690 to 965 MPa, a yield strength of 480 MPa, and can reach a hardness of up to 45 HRC after heat treatment. It offers excellent oxidation resistance up to 650°C and maintains its structural integrity even under mechanical stress. SS 422 Bolts also show good creep resistance, moderate corrosion resistance, and outstanding toughness in high-temperature applications, making them ideal for securing components that face heat and pressure.
