Punit Fasteners, a prominent manufacturer and supplier located in Delhi, India, specializes in high-quality Stainless Steel 310H Stud Bolts that are engineered for exceptional performance in extreme high-temperature settings. SS 310H is a high-carbon, heat-resistant austenitic stainless steel, celebrated for its remarkable strength and oxidation resistance even at elevated temperatures. These stud bolts are perfect for use in thermal processing, petrochemical facilities, power plants, and furnace operations. With a commitment to precision and quality, Punit Fasteners offers SS 310H stud bolts in a variety of lengths, thread types, and surface finishes, meeting the needs of industries that demand secure and dependable high-temperature fastening solutions.
Stainless Steel 310H Stud Bolts are made up of 24–26% chromium, 19–22% nickel, and a higher carbon content (≥0.04%) compared to standard SS 310, which boosts their creep resistance at high temperatures. These bolts deliver a tensile strength ranging from 515 to 750 MPa and a yield strength between 205 and 350 MPa. SS 310H excels in oxidation resistance up to 1150°C and retains its structural integrity during thermal cycling and high-pressure situations. The alloy is non-magnetic when annealed and is resistant to carburization, scaling, and thermal fatigue, making it an excellent choice for demanding heat service and high-load structural applications.
