310 Stainless Steel Seamless Pipes

ASTM A/ASME SA213/A249/A269/A312/A358 CL. I to V ASTM A789/A790 TP 310 Stainless Steel Pipes and Tubes

Grade 310, combining excellent high temperature properties with good ductility and weld ability, is designed for high temperature service. It resists oxidation in continuous service at temperatures up to 1150⁰C provided reducing sulphur gases are not present. It is also used for intermittent service at temperatures up to 1040⁰C.

Corrosion Resistance of 310 Stainless Steel Pipes and Tubes

The high chromium content - intended to increase high temperature properties - also gives these grades good aqueous corrosion resistance. The PRE is approximately 25, and seawater resistance about 22⁰C, similar to that of Grade 316. Excellent resistance at normal temperatures, and when in high temperature service exhibits good resistance to oxidizing and carburizing atmospheres. Resists fuming nitric acid at room temperature and fused nitrates up to 425⁰C.Subject to stress corrosion cracking but more resistant than Grades 304 or 316.

Heat Treatment of 310 Stainless Steel Pipes and Tubes

Solution Treatment (Annealing) - heat to 1040-1150⁰C and cool rapidly for maximum corrosion resistance. This treatment is also recommended to restore ductility after each 1000 hours of service above 650⁰C, due to long term precipitation of brittle sigma phase.

These grades cannot be hardened by thermal treatment.
