A312 TP310H Stainless Steel Polished Pipe
GNEE offers a wide range of A312 TP310H Austenitic Steel Pipe, these pipes are made of high quality raw materials to ensure consumption, resistance and sturdiness.
A312 TP310H Polished Stainless Steel Pipe has poor resistance to carbon and nitrogen absorption compared to high grade alloys. But 24% chromium and 19% nickel provide excellent corrosion resistance to A312 SS 310H Polished Pipe.
A312 TP310H High Temperature Polished Pipe has a hardness of 225HB, maximum temperature of 1900°F on the Brinell Hardness Scale and is recommended for cyclic conditions. Hence it is widely used in petrochemical plants in operations involving severe thermal cycles such as rapid air cooling.
