With high chromium and nickel content, SS 310 offers excellent resistance to oxidation, scaling, and corrosion, even under prolonged exposure to high temperatures.
We provide SS 310 square bars in a range of sizes and surface finishes, conforming to ASTM A276, ASME SA479, and EN 10088 standards. Each bar is delivered with full traceability and quality certifications.
What is SS 310 Square Bar?
SS 310 is an austenitic stainless steel alloy designed for high-temperature applications. It is especially effective in conditions involving continuous or intermittent heating up to 1150°C. The high chromium (24–26%) and nickel (19–22%) content improves its resistance to oxidation, carburization, and corrosion, making it ideal for furnace parts, kilns, and heat treatment fixtures.
