310S round bars, a heat-resistant austenitic stainless steel (UNS S31008), are engineered for exceptional performance in high-temperature environments where oxidation and carburization pose challenges. With a chromium-nickel composition (24-26% Cr, 19-22% Ni), this alloy forms a stable oxide layer, resisting scaling up to 1,200°C, making it ideal for furnace parts, exhaust systems, and heat treatment equipment. Newstar Hardware’s 310S round bars, manufactured to ASTM A276 and A479, offer a minimum tensile strength of 515MPa and yield strength of 205MPa, with elongation over 40% for formability. The alloy’s austenitic structure ensures non-magnetic properties and good ductility at elevated temperatures, suitable for components like furnace rails, muffles, and radiant tubes. Its resistance to intergranular corrosion (achieved through low carbon content <0.08%) maintains integrity in welded joints, while high-temperature creep strength supports load-bearing applications. Available in diameters from 10mm to 200mm, with hot-rolled or cold-finished surfaces, these bars cater to precision machining needs. Rigorous testing includes grain size analysis and oxidation resistance checks, ensuring reliability in petrochemical, glass, and heat treatment industries where materials must withstand extreme thermal cycles.
