Rithav Pipes and Tubes stands out as a top manufacturer and supplier in India, specializing in high-quality Stainless Steel 309H Tubing, designed to excel in high-temperature and corrosive industrial settings. The 309H variant is a high-carbon form of 309 stainless steel, which boosts its creep resistance and mechanical strength when the heat is on. This tubing is perfect for use in heat exchangers, boilers, furnaces, and thermal processing equipment. With its impressive resistance to oxidation and sulfidation, 309H tubing can handle continuous service temperatures of up to 1000°C (1832°F). Rithav offers this tubing in seamless, welded, and custom-fabricated options, all adhering to ASTM A213 / A269 standards.
When it comes to composition and mechanical properties, Stainless Steel 309H Tubing is made up of about 22–24% chromium, 12–15% nickel, and a higher carbon content (around 0.04–0.10%) to enhance its strength at high temperatures. This alloy also contains trace amounts of manganese, silicon, and phosphorus. Notable mechanical properties include a tensile strength of at least 550 MPa, yield strength of at least 205 MPa, and an elongation of at least 35%. The tubing boasts excellent thermal stability, oxidation resistance, and mechanical integrity in high-heat and mildly corrosive environments. Its elevated carbon content significantly improves creep strength, making it a great fit for pressure-retaining components under thermal stress.
