309S Stainless Steel Soft Wire
309S Stainless Steel Soft Wire
Description:
Type 309S is an austenitic chromium nickel stainless steel (.08% max carbon).Type 309is employed for parts requiring both corrosion and heat resistance and oxidation resistance up to 2000ºF. Strength at elevated temperatures is similar to that of 18-8 Stainless Steels.This alloy posses excellent resistance to oxidation as well as high tensile and creep strengths at elevated temperatures.

Physical Properties:
Annealed:
Ultimate Tensile Strength: 75 KSI min (620 MPA min)
Yield Strength (0.2% offset): 30 KSI min (205MPA min)
Elongation: 40% min
Hardness: Rb 95 max
Cold Forming:
Type 309 can be rolled formed, stamped and drawn readily. In-process annealing is usually required to reduce hardness and increase ductility.
Heat Treatment:
Type 309 can only be hardened by cold working.
