STAINLESS STEEL ALLOY 309
Stainless Steel Alloy 309 is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. the metal excels at resisting oxidation up to 1900°F (1038°C) under non-cyclic conditions. Due to the high chromium and low nickel content, Stainless Steel Alloy 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). However, the metal is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. Stainless Steel Alloy 309 can be processed by standard shop fabrication methods and is also easily welded.
