310S Stainless Steel Coil Heat Resistant 2B Finish ASTM A240 0.8mm 3.0mm Thickness 1000mm 1500mm Width High Temp Grade

ASTM A240 310S Stainless Steel Coil - Heat Resistant Grade

Grade 310S is a high-alloy austenitic stainless steel designed for elevated temperature service. With 25% chromium and 20% nickel content, it offers outstanding oxidation resistance and maintains structural integrity under continuous operation up to 1100°C in oxidizing atmospheres.

Key Features

• Exceptional High Temperature Performance: Maintains mechanical properties at temperatures up to 1100°C in continuous service
• Superior Oxidation Resistance: High Cr-Ni content forms a protective chromium oxide layer resistant to scaling at elevated temperatures
• Low Carbon 310S Variant: Reduced carbon content (max 0.08%) minimizes carbide precipitation and sensitization risks
• Thermal Fatigue Resistance: Excellent resistance to cyclic heating and cooling thermal stresses
• Good High Temperature Strength: Superior creep and stress rupture properties compared to standard 304/316 grades
• Carburization Resistance: Effective in CO/CO2 and hydrocarbon atmospheres at high temperatures

Typical Applications

• Furnace components, burners, and radiant tubes
• Heat treatment baskets, trays, and fixtures
• Kiln liners and kiln furniture
• Thermal oxidizers and incinerators
• Power generation boiler components
• Petrochemical cracking furnace tubes

Quality Assurance

All coils are verified through optical emission spectrometry for chemical composition, elevated temperature tensile testing, and oxidation resistance testing. Complete mill test certificates with full traceability provided in accordance with EN 10204 Type 3.1.
