Based in Delhi, India, Harshita Stainless is a top producer and supplier of stainless steel 316H nuts, providing high-end fastener solutions designed for applications requiring high temperatures and pressures. Harshita Stainless is well-known for their fine craftsmanship and commitment to global standards. They provide SS 316H nuts that are strong, resistant to corrosion, and perfect for demanding settings. The company serves sectors like petrochemicals, chemical processing, oil and gas, and power generation with a strong infrastructure and committed staff. Harshita Stainless has established a solid reputation in both domestic and foreign markets thanks to its dedication to accuracy, performance, and prompt delivery.
Stainless steel 316H nuts have a higher carbon content (up to 0.10%) than 316/316L, which improves high-temperature strength, and are made of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%). These nuts have exceptional mechanical qualities, such as yield strength of about 205 MPa and tensile strength of about 515 MPa. At higher temperatures, the increased carbon content offers better stability and resistance to creep. Applications involving constant exposure to high temperatures and demanding industrial conditions can benefit from the excellent corrosion resistance of SS 316H nuts, particularly in chloride and acidic environments.
