ASTM A240 309S stainless steel plate Processing:
These alloys are not hardenable by heat treatment. Anneal at 1900 - 2050°F (1038 - 1121°C), then water quench or rapidly air cool.
ASTM A240 309S stainless steel plate Forming:
Types 309 and 309S Stainless Steels can be roll formed, stamped and drawn readily. In-process annealing is usually required to reduce hardness and increase ductility.
