Alloy 309/309S (UNS S30900/S30908) austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.

Because of its high chromium and low nickel content, Alloy 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The alloy is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. Alloy 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.

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:

  • Boiler baffles
  • Furnace components
  • Oven linings
  • Fire box sheets
  • Other high temperature containers.
