Premium-grade stainless steel 304H bolts made for high-temperature and high-pressure applications are available from Vinit Stainless, a well-known stainless steel fastener manufacturer and supplier with headquarters in Chennai, India. In harsh industrial settings, our SS 304H bolts are designed to provide exceptional mechanical strength and resistance to oxidation. Precision manufacturing, global quality standards, and reliable performance are our top priorities at Vinit Stainless in order to serve customers in the petrochemical, construction, and power generation sectors. We are a reputable supplier in both domestic and international markets because our 304H bolts offer a dependable fastening solution where high temperatures and structural integrity are crucial.
High-carbon stainless steel 304H bolts have a carbon content of 0.04 to 0.10 percent, which increases their strength at high temperatures. Nickel (8–11%) and chromium (18–20%) make up the usual composition, which provides good resistance to oxidation and corrosion. These bolts have an approximate elongation of 40%, a yield strength of 240 MPa, and a tensile strength of 585 MPa. Even when subjected to heat stress, their austenitic structure guarantees exceptional toughness. SS 304H bolts are perfect for structural and pressure applications at high temperatures because of their enhanced creep resistance due to their higher carbon content.
