Anucha Metals is a leading Stainless Steel 310 Bars manufacturer in Bangkok, Thailand, providing bars engineered for extreme heat and oxidation resistance. SS 310 is an austenitic stainless steel designed for high-temperature applications, offering outstanding resistance to creep, scaling, and thermal cycling. Our 310 stainless steel bars are available in round, flat, square, and hex forms, adhering to ASTM A276, A479, and ASME specifications. These bars are suited for furnace components, thermal processing, and heat exchangers, where the materials have to function within continuous exposure to high temperatures.
SS 310 has 24–26% chromium, 19–22% nickel, and ~0.25% carbon. It provides tensile strength ~520 MPa, yield strength ~205 MPa, and structural integrity at temperatures up to 1150°C. SS 310 is an excellent oxidation-resistant alloy, has thermal strength, and is non-magnetic when annealed. SS 310 is also good at welding and resistant to sulfidation and carburization.
