ASTM A213 A312 A789 Grade 309S Stainless Steel Pipe Seamless Pipe Tube ANSI B36 SS Pipe
Alloys 309 and 309S are austenitic chromium-nickel stainless steel steels that will be commonly used for much higher temperature applications. Because of their higher chromium and also nickel content, Alloys 309 and also 309S are high rust resistant, have excellent resistance to oxidation, and also outstanding heat resistance when offering good energy at room and increased temperature ranges. The only major difference between 309 with 309S is the carbon content. Alloy 309S have a very much less carbon components which decreases carbide precipitation and also enhances weldability.

309 Stainless Steel Machinability
Grade 309 stainless steel can be machined similar to that of 304 stainless steel.
309 Stainless Steel Welding
Grade 309 stainless steel can be welded using fusion or resistance welding methods. Oxyacetylene welding method is not preferred for welding this alloy.
309 Stainless Steel Hot Working
Grade 309 stainless steel is hot worked at 1177°C (2150°F) followed by reheating at 982°C (1800°F). It can be then quenched rapidly. Post-work annealing can be done to restore its corrosion resistance property.
309 Stainless Steel Cold Working
Grade 309 stainless steel can be headed, upset, drawn, and stamped even though it has high work hardening rate. Annealing is performed after cold working in order to reduce internal stress.
309 Stainless Steel Annealing
Grade 309 stainless steel is annealed at 1038-1121°C (1900-2050°F) followed by quenching in water.
309 Stainless Steel Hardening
Grade 309 stainless steel does not react to heat treatment. Strength and hardness of this alloy can be increased by cold working.
309 Stainless Steel Applications
Grade 309 stainless steel is used in the following applications:
309 Stainless Steel Seamless Pipes and Tubes is sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation. SS 309 ASTM A312 Seamless Pipe packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.
Delivery: Within 10-25 days or asap if we have enough stock
