310S High Temperature Stainless Steel Sheet with 1150°C Service Temperature and Oxidation Resistance for Industrial Furnaces

Our 310S High Temperature Stainless Steel Sheet is the premier choice for applications demanding continuous exposure to extreme temperatures. With 25% chromium and 20% nickel content, this austenitic grade maintains structural integrity and oxidation resistance at temperatures up to 1150°C in continuous service, making it ideal for industrial furnaces, heat exchangers, and thermal processing equipment.

• Exceptional High Temperature Strength: Maintains mechanical properties at temperatures where standard grades fail, with excellent creep rupture strength
• Superior Oxidation Resistance: High chromium content forms a dense protective oxide layer that resists scaling up to 1150°C in air
• Carburization Resistance: High nickel content provides excellent resistance to carbon absorption in carburizing atmospheres
• Thermal Fatigue Resistance: Low coefficient of thermal expansion minimizes thermal stress cracking during heating and cooling cycles
• Weldability: Readily weldable using common fusion and resistance welding techniques with matching filler metals

• Industrial furnace components
• Heat exchanger tubesheets
• Thermal oxidizers
• Kiln liners and supports
• Annealing boxes
• Burner components
• Petrochemical processing equipment
• Power generation boilers
• Aerospace heat shields

All sheets undergo complete chemical analysis via OES, elevated temperature tensile testing, oxidation weight gain testing per ASTM G54, and ultrasonic thickness gauging. Full EN 10204 3.1 certification provided with every order.
