What is 309S stainless steel?
Alloy 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).
