309S round head square neck bolt supplier 309S Mechanical Properties
Alloy 309 (UNS S30900) is an austenitic stainless steel developed for high temperature corrosion resistant applications. The alloy resists oxidation up to 1900¡ãF (1038¡ãC) under non-cycling conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850¡ãF (1010¡ãC).
Alloy 309/309S is an austenitic chromium-nickel heat-resistant stainless steel with good oxidation resistance up to 1038¡ãC.
