ATI 309/ATI 309S/ATI 310/ATI 310S Steels

Steel name: ATI 309/ATI 309S/ATI 310/ATI 310S
Diagram No.: 2247
UNS designation: S30900/S30908/S31000/S31008
Chemical composition in weight %: See the table.
Steel group: Austenitic stainless steels
Properties: ATI 309 and ATI 310 austenitic stainless steels are typically used for elevated temperature applications. Their high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304.
Applications: Higher alloyed stainless steels generally exhibit excellent elevated temperature strength along with resistance to creep deformation and environmental attack. As such, they are used widely in the heat treatment industry for furnace parts such as conveyor belts, rollers, burner parts, refractory supports, retorts and oven linings, fans, tube hangers, and baskets and trays to hold small parts. These alloys are also used in the chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide. In the food processing industry, they are used in contact with hot acetic and citric acid.
