The Fasteners Mart, with its head office in Mumbai, India, is a leading manufacturer and exporter of industrial fasteners, renowned for quality, precision, and customer confidence. Among our specialty range is Stainless Steel 316H Bolts, made from high-carbon austenitic stainless steel. These bolts come in a range of shapes and sizes and are suited for high-pressure and high-temperature uses. The Grade 316H material has superior mechanical strength and resistance to corrosion and oxidation and is extremely suitable for application in industries like petrochemical, marine, and thermal processing plants.
Stainless Steel 316H Bolts consist mainly of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), and a slightly higher carbon content (0.04–0.10%) to enhance strength. They possess tensile strength of about 515 MPa, yield strength of 205 MPa, and hardness of up to 217 HB. Their density is 8.0 g/cm³ and offers very good high-temperature and corrosion resistance. The physical and mechanical properties render them suitable for prolonged service in the elevated temperature environments and corrosive environments.
