304 316L Stainless Steel Sanitary Pipe Seamless Cold Rolled and Polished
310, 310S and 310H stainless steel is an austenitic stainless steel designed for high temperature applications, capable of continuous service up to 2,100°F. This grade contains 25% chromium and 20% nickel, providing exceptional resistance to oxidation and corrosion.
310S stainless steel is the lower carbon version of 310 plate, offering reduced susceptibility to embrittlement and sensitization during service. 310H stainless steel plate is the high carbon variant. These grades are widely used in moderately carburizing atmospheres, particularly in petrochemical environments.
Not recommended for frequent liquid quenching due to thermal shock susceptibility, these grades are often utilized in cryogenic applications because of their toughness and low magnetic permeability.
