309 Stainless Steel 309 Stainless Steel Supplier At Stainless Shapes we provide the highest quality stainless steel. We are a proud 309 Stainless Steel supplier. 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. Furthermore, the 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 Machinability: This alloy machines similarly to type 304 stainless. The stringy chips produced by this material rapidly cause work hardening. To maintain optimal forming, it is essential to keep the cutting tools engaged and use chip breakers. Welding: Welding Grade 309 stainless steel requires fusion or resistance welding methods to achieve optimal hardness. Avoid using the oxyacetylene welding method. Formability: Grade 309/S stainless steel can be easily roll formed, stamped, and drawn. Annealing may be necessary to reduce hardness and enhance ductility. This type remains stable and non-magnetic even after cold working. Its lower elongation makes it more challenging to form compared to other Austenitic 300 grades. Not Sure What You are Looking For?
