Rithav Pipes and Tubes, based in Delhi, India, is a well-respected manufacturer and supplier of top-notch Alloy Steel T91 Tubing, specifically crafted for high-pressure and high-temperature applications in critical industries. T91 is a unique ferritic-martensitic alloy steel that includes chromium and molybdenum, providing outstanding creep strength, oxidation resistance, and durability against thermal fatigue. Adhering to ASTM A213 and ASME SA213 standards, Rithav offers T91 seamless tubing in a variety of sizes and wall thicknesses, perfect for power plants, boilers, heat exchangers, and petrochemical uses. These tubes are built to last in tough thermal conditions, ensuring superior structural integrity.
Alloy Steel T91 Tubing generally consists of 8–9.5% chromium, 0.85–1.05% molybdenum, 0.18–0.25% vanadium, along with trace amounts of niobium, nitrogen, and carbon (around 0.08–0.12%). This specific blend boosts creep rupture strength, oxidation resistance, and performance at high temperatures. The mechanical properties include a tensile strength of at least 585 MPa, yield strength of at least 415 MPa, and an elongation of at least 20%. These tubes maintain excellent mechanical stability even at temperatures reaching 600–650°C, making them ideal for continuous thermal stress. T91 is provided in a normalized and tempered state, ensuring improved microstructural stability and weldability for demanding applications.
