Stainless Steel 310 and 310S EFW Pipes Manufacturer, Supplier and Exporter in Delhi, India

Rithav Pipes and Tubes is a well-respected manufacturer and supplier of Stainless Steel 310 and 310S EFW Pipes based in Delhi, India. They specialize in providing high-performance piping solutions designed to withstand extreme heat and corrosive environments. These Electric Fusion Welded (EFW) pipes are crafted from heat-resistant austenitic stainless steel grades, renowned for their outstanding resistance to oxidation and scaling, even at temperatures reaching 1100°C. The main difference between SS 310 and 310S lies in their carbon content, with 310S offering better weldability and less carbide precipitation. Rithav’s EFW pipes comply with ASTM A358 standards and are essential in critical sectors like petrochemical, power, furnace, and thermal processing.

Stainless Steel 310 and 310S EFW Pipes are made up of chromium (24–26%), nickel (19–22%), carbon (≤0.25% in 310, ≤0.08% in 310S), and iron as the primary component. The high levels of chromium and nickel grant these pipes exceptional resistance to oxidation and thermal stress. They boast a tensile strength of at least 515 MPa, yield strength of at least 205 MPa, and an elongation of 40%. The lower carbon content in SS 310S enhances its weldability and reduces the risk of sensitization. These mechanical and corrosion-resistant features make them perfect for high-temperature structural and fluid transfer applications.
