Stainless Steel 309 is an austenitic stainless steel developed for use in high temperature corrosion resistance applications.

Stainless Steel 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy 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, SS 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The steel is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. UNS S30900 Steel can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. When heated between 1202 – 1742°F (650 – 950°C) the alloy is subject to sigma phase precipitation. A solution annealing treatment at 2012 – 2102°F (1100 – 1150°C) will restore a degree of toughness. 309 Stainless Steel can be easily welded and processed by standard shop fabrication practices.
