310S Stainless Steel Round Pipe
Langsda Metal Products Co.,Ltd supply excellent high temperature oxidation resistance Good for continuous exposure to 2100 degree F Intermittent service to 1900 degree F
Description
Grade 310S 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 2100째F. The higher chromium and nickel content, also makes it superior to 304 or 309 stainless pipes.
Grade 310 resists oxidation and is also used at temperatures up to 1040 degrees Celsius intermittently. Similar to other austenitic steel grades, toughness down to cryogenic temperatures is another feature of 310.
