Impex Tube India, having its headquarters in Mumbai, is a leading producer and supplier of high-quality pipes and tubes with high-performance features for critical industrial applications. Two of its hallmark products are Stainless Steel 310 and 310S Seamless Pipes, which stand out for their high temperature resistance and oxidation properties. These seamless pipes are made to exact international standards and have extensive usage in industries like power, petrochemicals, and heat treatment. With an emphasis on accuracy, quality control, and satisfaction of customers, Impex Tube India has established a strong reputation within the domestic as well as international markets.
Stainless Steel 310 and 310S Seamless Pipes are high-alloy austenitic stainless steels containing chromium (24–26%) and nickel (19–22%), with superior oxidation and corrosion resistance at high temperatures. The distinguishing factor is that 310S contains less carbon (maximum 0.08%), which enhances weldability and minimizes sensitization risk. These tubes display good mechanical properties, such as a minimum tensile strength of 515 MPa and a yield strength of 205 MPa. Owing to their superior ductility, toughness, and thermal stability, they can be employed in high-stress, high-temperature applications.

Stainless Steel 310 and 310S Seamless Pipes have extensive applications in industries that operate in harsh heat and corrosive conditions. Applications include furnace fittings, heat exchangers, radiant tubes, and combustion chamber components, where oxidation resistance is important. The pipes are employed in boilers, superheaters, and reformers in petrochemical and power generation industries. 310S, which has lower carbon content, is particularly favored in welded construction under corrosive environments. These pipes are also ideal for incinerators, kiln linings, and thermal processing equipment. They are durable and thermally resistant, making them a good option for aerospace, marine, and chemical processing industries.
