Harsh Metalloys, a prominent manufacturer and supplier located in Mumbai, India, specializes in high-quality Stainless Steel 422 Bolts designed for high-temperature and high-stress applications. SS 422 is a hardenable martensitic stainless steel that strikes a perfect balance between strength, corrosion resistance, and heat resistance. These bolts are perfect for use in turbines, aerospace, thermal processing, and power generation sectors. Built to meet international standards like ASTM and ASME, our 422 bolts come in various sizes and threading options. They deliver exceptional mechanical performance, especially after heat treatment, making them ideal for critical fastening tasks in extreme conditions.
Stainless Steel 422 Bolts generally contain 11–13% Chromium, 0.20–0.30% Carbon, 0.50–1.00% Manganese, along with Molybdenum, Nickel, and Tungsten to boost strength and heat resistance. This alloy can be heat treated to reach a tensile strength exceeding 860 MPa and hardness levels up to 45 HRC. SS 422 boasts impressive oxidation and scaling resistance up to 1200°F (649°C), along with solid corrosion resistance in mildly aggressive environments. These characteristics make 422 bolts perfect for high-stress and elevated-temperature applications in aerospace and thermal systems.
