Aditya Stainless, located in Kolkata, India, stands out as a leading manufacturer and supplier of Stainless Steel 422 Fasteners. These fasteners are celebrated for their remarkable strength, heat resistance, and reliability, even in the toughest operating conditions. Crafted from a hardened martensitic stainless steel alloy, they excel in high-temperature and high-stress environments. With a focus on precision engineering, these SS 422 fasteners boast corrosion resistance and impressive dimensional stability, making them perfect for critical industrial applications. Aditya Stainless offers a variety of fasteners—bolts, nuts, screws, and studs—customized for industries like aerospace, power generation, and turbomachinery.
Stainless Steel 422 Fasteners are made up of 12–14% chromium, 0.2–0.4% carbon, 0.5–1% molybdenum, along with trace amounts of nickel, tungsten, and vanadium, which boost hardenability and creep resistance. These fasteners can achieve a tensile strength of up to 950 MPa, a yield strength of at least 620 MPa, and a hardness of up to 45 HRC after proper heat treatment. SS 422 maintains its mechanical integrity at elevated temperatures reaching up to 650°C. It also showcases excellent fatigue strength, oxidation resistance, and dimensional stability, making it ideal for structural applications that face repeated thermal and mechanical loads.
