309, 309S, 309H S30900, S30908, S30909, AUSTENITIC Cr-Ni HEAT RESISTING STEEL

Description

309 provides excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. The alloy is non-magnetic as annealed and becomes slightly magnetic when cold worked.

309S Stainless Steel is known for its resistance to oxidation possesses better creep strength than Type 304/304L. Type 309S is commonly used in high temperature situations, including furnaces, kilns, boilers, and fire boxes. Type 309S is also used in the chemical industry.

Applications

309 stainless steel is mainly used for elevated temperature applications. Furnace parts - conveyor belts, rollers, burner parts, refractory supports, retorts and oven linings, fans, tube hangers, baskets and trays to hold small parts; Containers for hot concentrated acids, ammonia and sulfur dioxide; contact with hot acetic and citric acid.

Alloy 309S is used by the environmental, chemical processing and refining industries. Some equipment made with 309 includes: incinerators, furnaces, burners, kilns, annealing and carburizing boxes, combustion chambers, salt pots, thermo wells, gas turbines, retorts, flairs and equipment to handle sulfite liquors.
