TP310H Stainless Steel Pipes & Tubes

Material Description UNS S31009 Chemical Composition, % C Mn P S Si Cr Ni .04-0.10 2.0 .045 .03 1.0 24.0-26.0 19.0-22.0 TP310H is an austenitic, stainless chromium-nickel steel suitable for high-temperature applications. It has a good resistance to carburization, sulphidation and oxidation combined with moderate creep strength and structural stability. It has a maximum service temperature in air of 1100°C (2010°F). Corrosion Resistance TP310H 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 whether impurities such as sodium and vanadium are present

The high chromium content of TP310H makes the material resistant to oxidizing aqueous solutions. TP310H also has better resistance to chloride induced stress corrosion cracking than lower alloyed steels of type TP304 and TP316.

TP310H 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
