Harsh Metalloys is a leading manufacturer and supplier of Stainless Steel 316H Pipes in Mumbai, India, offering premium quality piping solutions for high-temperature and high-pressure environments. These pipes are made from stainless steel grade 316H, a high-carbon version of SS 316, providing enhanced strength and excellent resistance to oxidation and corrosion. Known for their superior mechanical properties and durability, SS 316H pipes are widely used in chemical processing, power generation, oil & gas, and refinery industries. Available in various sizes, wall thicknesses, and specifications, our SS 316H pipes comply with ASTM, ASME, and other international standards for reliability and performance.
Stainless Steel 316H Pipes are composed of Chromium (16–18%), Nickel (10–14%), Molybdenum (2–3%), and higher Carbon content (0.04–0.10%) than standard 316, which boosts high-temperature strength. They exhibit a minimum tensile strength of 515 MPa and yield strength of 205 MPa, with excellent creep and stress rupture properties. These pipes maintain stability in environments up to 870°C, making them ideal for elevated-temperature service. Additionally, SS 316H pipes offer excellent weldability, formability, and corrosion resistance in acidic and chloride-containing atmospheres.
