With its main office in Kolkata, India, Aditya Stainless is a well-known producer and supplier of high-quality stainless steel fasteners that cater to a variety of Indian industries. The Stainless Steel 422 Stud Bolt, designed for applications needing both high strength and resistance to harsh conditions, is one of its most notable products. These stud bolts, which are made of martensitic stainless steel grade 422, are perfect for high-temperature and high-pressure settings. Aditya Stainless is a preferred partner for demanding mechanical and structural fastening needs because of their strong emphasis on quality and customer satisfaction, timely delivery, and precision manufacturing.
The martensitic stainless steel alloy used to make Stainless Steel 422 Stud Bolts has roughly 11–13% chromium, 0.2–1% molybdenum, 0.2–0.5% vanadium, and 0.2–0.4% carbon. These components help explain their exceptional wear and heat resistance as well as their high tensile strength, which is normally between 620 and 830 MPa. The alloy can function at temperatures as high as 600°C and has good corrosion resistance. 422 stainless steel bolts are appropriate for demanding mechanical assemblies because of their good toughness, resistance to oxidation and creep, and ability to be heat treated to improve their mechanical qualities.
