Home > Stainless Steel Tubing > Stainless Steel 348 Tubing
Based in Chennai, India, Vipul Pipes and Tubes is a reputable manufacturer and supplier that is well-known for providing premium stainless steel 348 tubing to satisfy the exacting requirements of numerous industries. The company offers tubing solutions that perform well in corrosive and high-temperature environments, with an emphasis on quality, durability, and accuracy. Niobium-stabilized austenitic stainless steel, known as Stainless Steel 348 Tubing, provides exceptional resistance to intergranular corrosion. Serving customers in industries including nuclear energy, chemical processing, aerospace, and high-performance heat exchanger systems, Vipul Pipes and Tubes guarantees that every product satisfies international standards.
The main constituents of stainless steel 348 tubing are nickel (8–11%), chromium (17–20%), and trace amounts of niobium (columbium), which stabilises the alloy against intergranular corrosion. With a typical tensile strength of 515–750 MPa, yield strength of 205–310 MPa, and elongation of 30–40%, it possesses exceptional mechanical strength and heat resistance. Up to 870°C (1600°F), SS 348 maintains its structural integrity. It is perfect for high-temperature pressure systems because niobium increases its creep resistance. Its industrial versatility is further enhanced by its non-magnetic nature and good weldability.
