The Fasteners Mart, a Mumbai, India-based company, is a top supplier of high-quality industrial fasteners serving a broad spectrum of industries globally. We are well known for our precision-engineered products, and we specialize in providing high-performance fastening solutions made from quality materials. One of our products is the Stainless Steel 422 Stud Bolts, which is made from Grade 422 martensitic stainless steel. These stud bolts, characteristically cylindrical having threaded ends, have been proven for their toughness, oxidation resistance, and superior heat-resisting features, suiting them particularly to stringent industrial and mechanical engineering purposes.
Stainless Steel 422 Stud Bolts include chromium (11–13%), molybdenum (0.8–1.25%), tungsten, and carbon (0.2–0.25%), along with other elements such as silicon, manganese, and vanadium. They provide up to 950 MPa tensile strength and superior creep resistance at temperatures of up to 650°C. They possess physical properties such as a density of about 7.74 g/cm³ and retain structural strength under heat stress. The bolts are suitable for high-load and high-temperature applications calling for extended durability and strength.
