310 / 310S Stainless Steel Pipe

Grade 310 is an austenitic stainless steel, which offers exceptional high temperature properties, along with good ductility and weldability.
Type 310 stainless steel pipes are typically used for elevated temperature applications.
High chromium and nickel content of 310 grade steel pipes provides excellent resistance to corrosion and oxidation,
as well as superior strength in temperatures up to 2100°F. The higher chromium and nickel content, also makes it superior to 304 or 309 stainless pipes.
Grade 310S is a low carbon alternative of grade 310. It is used in a lower temperature range when the application environment involves moist corrodents.
However, the lower carbon content reduces the high temperature strength of stainless steel grade 310S compared to 310.
