Advantages
TP310S material is a high-grade austenitic stainless steel with excellent oxidation & carburization resistance, is widely used in extreme-temperature environments.
1.Exceptional High-Temperature Performance:
Withstands continuous service up to 1150°C (2100°F) and intermittent exposure to 1035°C (1900°F).
Superior oxidation & carburization resistance compared to 304/316, ideal for furnaces, kilns, and exhaust systems.
2.Outstanding Corrosion Resistance:
High chromium (25%) and nickel (20%) content resists
Key Applications
1.Petrochemical & Refining
· Crackers, reformers, and pyrolysis tube
· Catalyst support grids in harsh chemical environments
2.Power Generation
· Boiler superheaters & heat exchangers
· Waste-to-energy (WTE) plants for flue gas handling
· Nuclear auxiliary systems (non-core components)
3.High-Temperature Processing
· Furnace components (radiant tubes, muffles, rollers)
· Heat treatment & annealing equipment
· Kilns and ceramic firing systems
