310 Stainless Steel Tube – The Ultimate High-Temperature Tubing Solution for 1150 °C Continuous Service
When your process demands continuous exposure above 800 °C, only 310 Stainless Steel Tube 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 tube dramatically superior to 304, 316, or 321 in furnace radiant tubes, petrochemical crackers, and power-station superheaters worldwide.
