One of the top producers and suppliers of high-end stainless steel fasteners, such as Stainless Steel 310H Fasteners, is Vinit Stainless, which has its headquarters in Chennai, India. These fasteners have exceptional strength, resistance to oxidation, and resistance to creep because they are specifically made for high-temperature applications. Vinit Stainless produces fasteners that guarantee peak performance in harsh industrial settings by utilising cutting-edge manufacturing technology and paying close attention to international standards. Power plants, refineries, and thermal processing units—where heat and mechanical stress are ongoing challenges—trust our 310H fasteners. We are dedicated to offering strong, effective fastening solutions for challenging engineering applications.
High-carbon stainless steel 310H fasteners have a carbon content of between 0.04% and 0.10% and contain nickel (19–22%) and chromium (24%–26%). This extra carbon improves creep resistance and strength at high temperatures. These fasteners have an approximate elongation of 40%, a yield strength of 205 MPa, and a tensile strength of 515 MPa. Even at very high temperatures, the austenitic structure offers exceptional toughness. For structural elements in conditions above 1000°C, where mechanical integrity and heat resistance are crucial, SS 310H fasteners are especially well-suited.
