Harsh Metalloys is a trusted manufacturer and supplier of Stainless Steel 316H Bolts in Mumbai, India, delivering superior fastening solutions for critical industrial applications. Known for their enhanced strength and heat resistance, 316H bolts are crafted from high-carbon stainless steel, offering excellent performance in high-temperature environments. These bolts are precision-engineered to meet international standards such as ASTM A193 and ASTM F593, and are available in various sizes, threads, and finishes. Our 316H bolts are ideal for use in chemical processing, oil refineries, power plants, and other demanding industries requiring durable, corrosion-resistant fasteners.
Stainless Steel 316H Bolts are composed of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and a higher carbon content (0.04–0.10%) for increased strength at elevated temperatures. These bolts exhibit a tensile strength of approximately 515 MPa and yield strength of 205 MPa, with excellent elongation and toughness. The molybdenum improves resistance to pitting and crevice corrosion in chloride environments. Their austenitic structure provides good weldability and formability, while the high carbon content makes them suitable for applications involving high temperatures and pressures.
