Steel Plate Specification:
Thickness:0.3mm-100mm,
Width:200-3000mm.
Application:
309S Stainless Steel is used for its high-temperature oxidation resistance or resistance to H2S attack for applications.
309S Stainless Steel Introduction
Alloy 309S and Alloy 310S 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.
309S Stainless Steel Usage
It is 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. The grade is 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.
