Our SS 310 and 310S EFW Pipes are made from top-quality materials and advanced technology to provide excellent corrosion resistance, high-temperature functionality, and long-lasting service life. Our company, Ojas Pipes and Tubes, is known for its prompt deliveries, best prices, and compliance with national and international quality standards.
Stainless Steel 310 and 310S EFW Pipes are high-alloy austenitic stainless steels that contain mostly 25% chromium and 20% nickel. The 310S type has lower carbon content, which improves weldability and resistance to sensitization. The mechanical properties are tensile strength around 515 MPa, yield strength around 205 MPa, and elongation of 40% min. These pipes also exhibit high toughness and creep resistance even at high temperatures and are suitable for heat-intensive conditions. Their superior mechanical stability makes them dependable in high-stress conditions.
