310 / 310S Stainless Steel Pipe
Grade 310 is the combination of greater temperature properties along with weldability and ductility and is developed for high-temperature service. It is designed especially for the high temperatures services. It is resisting oxidation at continuous service temperature at 1150 Deg C provided and reducing sulphur gas isn’t present. It is used for an intermittent service at the temperature at 1040 Deg C.
Grade 310S is used when the applications atmosphere involves moist corrodent at the temperature ranging lower than that is considered normally high-temperature service. This grade low carbon content reduces high-temperature strength as compared to 310.
Stainless Steel 310S Seamless Tubes is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000 Degree F. Stainless Steel 310S Welded Pipes is commonly used in the heat treatment and process industries due to high temperature and corrosive environments.

The process of Seamless steel pipe:
Hot Rolled Process for Seamless Steel Pipe
Cold Drawn Process for Seamless Steel Pipe
The process of welded steel pipe:
Tube hangers and steam boilers, kilns, lead pots, fluidized bed combustors, and refractory anchor bolts are just a few of the applications for Grade 310 / 310S Pipes It’s also used to make retorts, muffles, cryogenic systems, and food processing equipment.
