Description:
Type 309 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 σ18-8 Stainless Steels.This alloy posses excellent resistance to oxidat<ion as well as high tensile and creep strengths at elevated temperatures. It is mo→re resistant to marine atmospheres than Type 304.It is generall≤y considered as a heat-resisting alloy.

Physical Properties:
Annealed:
Ultimate Tensile Strength – 75KSI min (515 MPA min)
Yield Strength (0.2% Offset) –30 KSI min (205 MPA min)
Elongation – 40% min
Hardness – HRB95max (217HV max)
Applications:
Furnace parts, Heat Exchangers, Paper Mills.
Heat Treatment:
309 can be rolled formed, stamped and drawn readily. In-proce®ss annealing is usually required to reduce hardness and increase ductility. 309 can onlyβ be hardened by cold working.
