309 Stainless Steel Plate Sheet Coil, ASTM A240 Stainless Steel 309 Plate, UNS S30900 Plate, Stainless Steel 309 Plate, SS 309 ASTM A240 309 Hot Rolled Plate, A240 309 Cold Rolled Plate.

The 309 Stainless Steel Plate produced by steel mills is more resistant to corrosion and high temperature. Can withstand high temperature of 980°C. Mainly used in boiler, chemical and other industries. Compared with 309S, 309 does not contain sulfur S content.

309 Stainless Steel Plate is made of an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The ASTM A240 Stainless Steel 309 Plate resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C). Because of its high chromium and low nickel content, UNS S30900 Plate can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). Stainless Steel 309 Plate is not recommended for use in highly carburizing atmospheres since Stainless Steel Plate exhibits only moderate resistance to carbon absorption. SS 309 ASTM A240 309 Hot Rolled Plate can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.
