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.
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
