310 Stainless Steel Pipe 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.
Grade 310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered "high temperature" service. The lower carbon content of 310S does reduce its high temperature strength compared to 310.
Like other austenitic grades these have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment.
Grade 310L (and proprietary versions of this grade), is a 0.03% maximum carbon version of 310, sometimes used for very specific corrosive environments, such as urea production.

These comparisons are approximate only. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted. |
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
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.
Applications of 310 Stainless Steel Pipes and Tubes
Typical applications include:
Furnace parts
Oil burner parts
Carburizing boxes
Heat Treatment baskets and jigs
Heat Exchangers
Welding filler wire and electrodes
