Hemi Metals, based in Hamilton, New Zealand, is a trusted name in the manufacturing and supply of high-performance Stainless Steel 310S Hollow Bars, designed to thrive in extreme temperatures and corrosive settings. Renowned for their precision in manufacturing and rigorous quality control, Hemi Metals ensures that their 310S hollow bars deliver remarkable oxidation resistance and a long lifespan. These bars find their place in furnace equipment, thermal processing systems, and heavy industrial fabrication. With a commitment to consistent material quality and reliable supply, Hemi Metals serves industries like petrochemical, power generation, heat treatment, and high-temperature engineering applications.
Stainless Steel 310S Hollow Bars are made up of about 24–26% chromium and 19–22% nickel, featuring low carbon content to enhance weldability and minimize carbide precipitation. The elevated levels of chromium and nickel grant exceptional resistance to oxidation, scaling, and heat corrosion. SS 310S boasts a tensile strength of around 520 MPa and a yield strength close to 205 MPa, along with impressive creep resistance at high temperatures. It retains good ductility, toughness, and structural integrity, even when subjected to continuous high-heat conditions.

The high chromium (25%) and nickel (20%) content in SS 310S enhances its resistance to corrosion by forming a protective oxide layer on the surface. This layer shields the material from aggressive environmental factors, preventing oxidation and corrosion in harsh conditions.
SS 310S Hollow Bars are commonly used in industries such as power generation, chemical processing, petrochemical, aerospace, and manufacturing. They are essential for components in high-temperature environments, including furnace parts, heat exchangers, boilers, reactors, and gas turbines.
Stainless Steel 310S Hollow Bars are tailored for high-temperature and cyclic heat applications where regular stainless steels fall short. They are widely utilized in furnace tubes, radiant burners, heat exchangers, thermal processing equipment, kilns, and components in petrochemical plants. SS 310S hollow bars are also essential in power plants, refinery piping systems, and gas processing units, where resistance to oxidation and scaling is crucial. Their capability to endure continuous exposure to temperatures exceeding 1000°C makes them perfect for annealing lines, combustion chambers, and high-heat structural supports.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
