Rithav Pipes and Tubes stands out as a top manufacturer and supplier of Stainless Steel 316H Welded Pipes, proudly based in Delhi, India. This high-carbon variant of 316 is crafted for remarkable strength, creep resistance, and stability even in high-temperature environments. Our welded pipes, made in accordance with ASTM A312 and ASME SA312 standards, boast impressive corrosion resistance, particularly in challenging conditions like chloride-rich, acidic, and marine settings. Rithav Pipes and Tubes provides these durable Stainless Steel 316H welded pipes for essential applications in petrochemical plants, refineries, chemical processing, power generation, and the food industry, ensuring reliable performance and solid weld integrity under tough conditions.
Stainless Steel 316H Welded Pipes are composed of about 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, with a higher carbon content (0.04–0.10%) that boosts high-temperature strength. They typically exhibit a tensile strength ranging from 515–690 MPa and a yield strength of around 205 MPa. This alloy excels in creep and stress rupture resistance at temperatures above 500 °C, along with outstanding pitting and crevice corrosion resistance in chloride-laden environments. The austenitic microstructure of 316H guarantees excellent toughness, weldability, and stability, even after extended exposure to high temperatures, making it perfect for demanding process and structural piping systems.
