310 Stainless Steel Plate – The Undisputed King of High-Temperature Stainless Plates for 1150 °C Service

When your furnace, kiln, or petrochemical reactor demands continuous exposure above 800 °C, only 310 Stainless Steel Plate delivers the reliability you need. With 25 % chromium and 20 % nickel, this austenitic grade forms a tenacious oxide scale that resists spalling even under cyclic thermal shock up to 1100 °C. Its high nickel content maintains austenitic stability, while chromium provides exceptional oxidation, sulfidation, and carburization resistance—making 310 stainless steel plate dramatically superior to 304, 316, or 321 in furnace bases, radiant tube sheets, and power-station boiler shields worldwide.
