310 /310S Cold Drawn Stainless Steel Rod

If you are looking for high-strength, heat-resistant stainless steel bars for furnace components, heat exchangers, petrochemical equipment, and other high-temperature industrial applications, GNEE supplies premium 310 / 310S cold drawn solid round bars manufactured in strict accordance with ASTM A276, ASTM A479, EN 10088-3, and JIS G4303 standards. Our products effectively address common challenges in high-temperature environments, such as deformation, insufficient creep strength, and short service life.

Our 310/310S cold drawn stainless steel bars are available in diameters ranging from 2mm to 50mm, with straightness controlled to ≤0.5 mm/m and surface roughness of Ra ≤0.8 μm. Produced through precision cold drawing, solution annealing, and straightening processes, these bars contain 24.0–26.0% chromium and 19.0–22.0% nickel, forming a fully austenitic structure specifically designed for extreme high-temperature service. The material is non-magnetic, offers good machinability, and delivers stable welding performance, meeting the strict requirements of high-precision mechanical parts and complex structural components.

With a low carbon content of ≤0.08%, 310S stainless steel round bars provide enhanced resistance to intergranular corrosion and improved weldability. They can operate continuously at temperatures up to 1150°C, significantly outperforming grades such as 304, 316, and 321 in high-heat environments. These bars are widely used in high-temperature furnaces, boiler components, heat treatment fixtures, kiln assemblies, and industrial heating equipment, delivering reliable performance and long service life under extreme thermal conditions.
