Stainless Steel 310H Bolts are the speciality of Vinit Stainless, a reputable manufacturer and supplier of high-end stainless steel fasteners in Chennai, India. Our SS 310H bolts are extensively utilised in the heat treatment, petrochemical, and power generation industries and are made for high-temperature and high-pressure settings. We make sure that every bolt satisfies international standards and can endure harsh operating conditions by placing a high priority on quality, accuracy, and customer satisfaction. Vinit Stainless is a favoured supplier in India and abroad because we provide dependable and long-lasting fastening solutions that perform exceptionally well in hot, oxidation-prone, and corrosive environments.
High-carbon (0.04–0.10%) stainless steel 310H bolts are made to withstand creep better at higher temperatures. They are composed of nickel (19–22%) and chromium (24–26%), which offer superior resistance to corrosion and oxidation. These bolts have good elongation (≥40%) and a tensile strength of about 515 MPa and a yield strength of about 205 MPa. 310H bolts are perfect for pressure vessels and high-temperature structural applications because of their austenitic structure, which guarantees toughness even in cryogenic conditions, and their increased carbon content, which enhances high-temperature strength.
