ASTM A312 TP310S Stainless Steel Compared to other Materials

• Compared to TP304/TP316: While TP310S may not have the optimal room temperature corrosion resistance, its high-temperature performance is far superior. It is not designed for room-temperature corrosive environments.
• Compared to TP321H: Both can be used at high temperatures, but TP310S has a higher chromium-nickel content, thus offering superior resistance to oxidation and carburization, and is typically used in furnace areas with higher temperatures and harsher atmospheres.
• Core Advantage: The irreplaceable nature of TP310S lies in its extremely high chromium content, making it the preferred economical alloy for operation in oxidizing and carburizing environments above 980°C.

ASTM A312 TP310S Stainless Steel Seamless Pipe Main Application

• High-Temperature Heat Treatment Equipment: Radiant tubes, furnace rollers, muffle tanks, thermocouple sheaths for industrial furnaces; components for carburizing and nitriding furnaces.

• Petrochemical and Chemical Industries: High-temperature pyrolysis furnace tubes, conversion furnace tubes; pipelines and heat exchangers for transporting high-temperature, highly corrosive media.

• Power Plants and Energy: Superheaters and reheaters for ultra-supercritical power plant boilers; waste gas recirculation systems; and high-temperature components for biomass power generation.

• Others: Waste incinerators, kiln equipment, high-temperature components for aerospace, etc.
