TP310S Stainless Steel Pipes & Tubes

Material Description UNS S31008 Chemical Composition, % C Mn P S Si Cr Ni .08 max 2.0 .045 .03 1.5 24.0-26.0 19.2-22.0 TP310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000ºF. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like TP304 Corrosion Resistance TP310S has very good resistance to oxidation and sulphidation. It can be used in ● Air up to 1100°C (2010°F) ● Sulphur-containing atmospheres up to 650-1050°C (1200-1920°F), depending on

service conditions. Factors to consider are whether the atmosphere is oxidizing or reducing and vanadium are present

The high chromium content of TP310S makes the material resistant to oxidizing aqueous solutions. TP310S also has better resistance to chloride induced stress corrosion cracking than lower alloyed steels of type TP304 and TP316.

TP310S has good resistance in cyanide melts and neutral salts melts at high temperature.

Application

• Furnace tubes

• Recuperator tubes

• Muffle tubes in continuous wire annealing furnaces

• Thermocouple protection tubes

• Radiant tubes

• Tube hangers in petroleum and steam boilers
