Stainless Steel 348 Pipes are among the premium stainless steel piping solutions offered by Vipul Pipes and Tubes, a well-known manufacturer and supplier with headquarters in Chennai, India. Applications needing resistance to intergranular corrosion and high thermal stress are best suited for SS 348 pipes, which are renowned for their exceptional mechanical strength and stability at high temperatures. Vipul guarantees that every pipe is made in accordance with global quality standards, providing reliable performance in sectors like power generation, nuclear energy, chemical processing, and aerospace. Vipul Pipes and Tubes is a reputable brand for long-lasting, precisely engineered stainless steel pipes, dedicated to both innovation and client satisfaction.
The stabilised austenitic stainless steel alloy known as Stainless Steel 348 Pipes is made up of 9–13% nickel, 17–19% chromium, and trace amounts of tantalum and niobium (Columbium). Particularly after welding, these stabilisers improve resistance to intergranular corrosion. The tensile and yield strengths of SS 348 are roughly 550–750 MPa and 240–310 MPa, respectively. It is perfect for thermal cycling environments because it retains exceptional strength and resistance to oxidation at high temperatures. For corrosive and high-heat industrial applications, such as pressure vessels and welded structures, 348 pipes offer a dependable solution due to their good formability and weldability.
