Neil Metals stands out as a top manufacturer and supplier of high-quality Stainless Steel 310 Hollow Bars, proudly based in Kolkata, India. Renowned for their resistance to high temperatures and oxidation, these hollow bars are designed to thrive in harsh heat and corrosive settings. At Neil Metals, we craft these bars with meticulous attention to detail and a strong commitment to international quality standards, catering to sectors like power generation, petrochemicals, furnaces, and thermal processing. Our stainless steel 310 hollow bars deliver exceptional strength, weldability, and durability, making them perfect for tough structural and mechanical applications. We’re dedicated to providing outstanding products, timely service, and tailored solutions to meet our clients’ needs.
Stainless Steel 310 Hollow Bars are made up of chromium (24–26%), nickel (19–22%), along with trace amounts of carbon, manganese, and silicon. This rich alloy composition ensures remarkable oxidation and creep resistance at temperatures soaring up to 1150°C. Typically, the alloy boasts a tensile strength of around 520 MPa, a yield strength of 205 MPa, and an elongation of 40%. With a Brinell hardness of about 217 HB, SS 310 retains its structural integrity and mechanical properties even when exposed to prolonged heat. Its austenitic structure also lends itself to good ductility and weldability, making it ideal for high-temperature industrial components.
