The business offers premium-grade fasteners made for high-temperature and high-pressure applications and has a solid reputation for accuracy and quality. To satisfy international standards, SS 304H Stud Bolts are produced utilising sophisticated procedures and strict quality controls. These bolts, which are widely used in refineries, petrochemical industries, and power plants, are renowned for their strength, resilience to corrosion, and durability. Vinit Stainless is a preferred supplier for essential industrial fastening solutions in India and around the world because of their prompt delivery, personalised sizes, and first-rate customer service.
The austenitic stainless steel alloy used to make 304H stud bolts has a high carbon content (0.04%–0.10%), 18–20% chromium, and 8–10.5% nickel. Creep resistance and high-temperature strength are improved by the higher carbon content. These stud bolts have good elongation, yield strength (about 205 MPa), and exceptional tensile strength (up to 515 MPa). Additionally, SS 304H is suitable for high-heat environments because it retains its toughness even at high temperatures. It is easily welded and fabricated using standard techniques, has good oxidation resistance, and is non-magnetic when annealed.
