At Stainless Shapes we provide the highest quality stainless steel, and that includes our line of 309 stainless steel. Alloys 309 and 309S are austenitic chromium-nickel steel. They are used for higher temperature applications. They have a high corrosion resistance due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.

Features of 309 Stainless

stainless-channelMachinability: This alloy machines similarly to type 304 stainless. Its chips are stringy, and it will work harden rapidly. It is necessary to keep the tool cutting at all times and use chip breakers to ensure optimal forming.

Welding: Grade 309 stainless steel can be welded using fusion or resistance welding methods and work best with its hardness. Oxyacetylene welding method is not preferred for welding this alloy.

Formability: Types 309/S stainless can be roll formed, stamped, and drawn easily. Annealing is sometimes required to reduce hardness and restore ductility. Type 309 is extremely stable and remains nonmagnetic when cold worked. Lower elongation makes this grade more difficult to form than other 300 Austenitic grades.
