Home > Stainless Steel Tubing > Stainless Steel 348H Tubing
A reputable company in Chennai, India, Vipul Pipes and Tubes is a top producer and supplier of stainless steel 348H tubing, which is renowned for its outstanding performance in corrosive and high-temperature conditions. The 348H grade is a stabilised austenitic stainless steel that is perfect for applications requiring extended exposure to high temperatures and is made to meet international quality standards. Vipul guarantees excellent quality, accurate production, and prompt delivery. Their 348H tubing solutions, which provide a long service life and reliable performance, are widely used in heat exchangers, petrochemical processing, and nuclear applications where strength, corrosion resistance, and thermal stability are crucial.
Stainless Steel 348H Tubing has a higher carbon content (up to 0.10%) than SS 348 and is made up of 17–20% chromium, 8–11% nickel, and additional columbium (niobium) and tantalum for stabilisation. At elevated temperatures, this stabilised alloy improves resistance to creep and intergranular corrosion. With a tensile strength between 515 and 750 MPa, a yield strength of at least 205 MPa, and a 30% elongation, the tubing demonstrates exceptional mechanical strength. 348H is appropriate for high-temperature, pressure-bearing applications because it retains its structural integrity and resistance to oxidation when used continuously above 800°C.
