Stainless Steel 347H Pipes & Tubes – Premium Supplier in India

At Sanjivini Steel Centre, we are a leading supplier and stockist of Stainless Steel 347H Pipes and Tubes in India, offering premium quality products at competitive prices. The SS 347H Welded Pipe is a high-carbon version of 347 stainless steel, designed for high-temperature and high-pressure applications. Known for excellent creep resistance, oxidation resistance, and superior mechanical strength, this grade is ideal for demanding industrial environments.

Our Stainless Steel 347H Pipes (UNS S34709 / WNR 1.4961) are stabilized with columbium, making them resistant to intergranular corrosion and sensitization, which commonly affect grades like 304 and 304L. With a carbon content ranging from 0.04 to 0.04–0.10%, the material allows for dual certification and excellent thermal stability. The 347H Seamless Pipes and ERW Pipes are available in a variety of dimensions (1/8” to 8” OD, ½” to 24” NB) and thicknesses (including Schedule 40), tailored to client-specific needs.

Manufactured using high-grade raw materials and advanced technology, our ASTM A312 TP347H Pipes, SA 312 TP347H Rectangular Pipes, and DIN 1.4961 Square Pipes find wide usage in oil & gas refineries, aircraft exhaust systems, cabin heaters, heat exchangers, and boiler casings. These pipes deliver excellent tensile strength (≥ 515 MPa), yield strength (≥ 205 MPa), and a Brinell hardness of 201.
