309 Stainless Steel
Products Offered in 309 stainless steel:
Principal Design Features: This alloy, 309 Stainless Steel, is known for good strength and oxidation resistance in continuous service temperatures up to 2000 F (1093 C).It is superior to 304 stainless in both strength and corrosion resistance.
Applications: Oven linings, boiler baffles, fire box sheets, furnace components and other high temperature containers.
Machinability: 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.
Welding: Most of the austenitic stainless steels can be readily welded using fusion or resistance methods. Oxyacetylene welding is not recommended. Filler metal should be AWS E/ER 309 or 309L.
