Alloy 309/309S 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 Alloy 304.

Alloy 309/309S Austenitic Stainless Steel
Alloy 309/309S Plate Common Size:
Thickness: 0.4mm-100mm
1000 x 2000mm
1220 x 2440mm
1250 x 2500mm
1500 x 3000mm To 6000mm
2000 x 4000mm To 6000mm
Alloys 309/309S plates are primarily used at elevated temperature to take advantage of their oxidation resistance. However, both of these stainless grades are resistant to aqueous corrosion due to their high chromium and nickel contents.
Although their higher nickel content provides marginal improvement with respect to chloride stress corrosion cracking (SCC) compared to the 18-8 stainless steels, Alloys 309/309S austenitic stainless steels remain susceptible to this form of attack.
Higher alloyed stainless steels generally exhibit excellent elevated temperature strength along with resistance to creep deformation and environmental attack. As such, Alloys 309/309S plate 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 grades 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.
