Heat Resistant 310S Stainless Steel Sheet for Industrial Furnace Lining

Heat Resistant 310S Stainless Steel Sheet is an austenitic stainless steel with approximately 25% chromium and 20% nickel, developed to survive continuous high-temperature service where ordinary 304 or 316 grades would oxidize and scale away. Its high chromium and nickel content gives it outstanding resistance to oxidation, carburization and thermal cycling, allowing it to operate reliably at temperatures up to about 1100 degrees Celsius. That makes it the standard material for industrial furnace linings, radiant tubes, retorts, and other components that must withstand intense heat without losing strength or forming heavy oxide scale. For plant operators, 310S means longer campaign life, less downtime and more predictable maintenance.

• Excellent High-Temperature Oxidation Resistance: Withstands continuous service up to about 1050 degrees Celsius and intermittent peaks to 1100 degrees.
• Resistance to Carburization: High chromium and nickel content resists carbon pickup and scaling in hot process atmospheres.
• Stable Austenitic Structure: Retains toughness and strength at elevated temperature without becoming brittle.
• Good Creep Performance: Suitable for furnace parts, retorts and radiant tubes under sustained thermal load.
• Reliable Weldability: Can be welded and fabricated into linings, supports and pipework.
• Full Traceability: Chemistry and mechanical properties verified by Mill Test Certificate.

310S sheet and plate are used for industrial furnace linings, burner parts, radiant tubes, retorts, heat-treatment trays and fixtures, annealing and carburizing boxes, cement and lime kiln components, exhaust systems and high-temperature flue ducting. In the petrochemical and power industries it serves for furnace internals and heat exchangers exposed to hot corrosive gases. Because it resists both oxidation and carburization, 310S extends the service life of components that operate in the hottest zones of a process, cutting the frequency of costly shutdowns for repairs and replacements.

Sheets and plates are supplied pickled or as rolled, protected where necessary with waterproof paper, stacked on steel or wooden pallets and secured with strapping for safe transport. Chemical composition, tensile properties and surface condition are checked before dispatch, and a Mill Test Certificate is issued for each heat number. We can supply standard plates as well as cut-to-size pieces and small trial quantities, so customers can validate welding and forming procedures before placing full orders.
