Harshita Stainless, based in Delhi, India, has earned a solid reputation as a reliable manufacturer and supplier of Stainless Steel 316H Fasteners. They provide top-notch fastening solutions tailored for demanding industrial applications. With a focus on precision engineering and strict adherence to international standards, the company excels in crafting fasteners that boast remarkable strength, durability, and resistance to corrosion. The high-carbon Stainless Steel 316H variant is particularly suited for high-temperature and high-pressure settings. Harshita Stainless offers these fasteners in a variety of sizes and specifications, catering to the specific needs of industries like petrochemical, power generation, marine, and construction, ensuring dependable and long-lasting performance in critical operations.
Stainless Steel 316H is a high-carbon austenitic stainless steel that includes 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and 0.04–0.10% carbon. The elevated carbon content boosts its strength at high temperatures and enhances creep resistance. SS 316H fasteners deliver a tensile strength ranging from 515–700 MPa, yield strength between 205–290 MPa, and an elongation of about 40–50%, with a hardness rating of 80–90 HRB. These characteristics make them perfect for high-pressure and heat-exposed environments while ensuring excellent corrosion resistance in acidic and chloride-rich conditions.
