High Temp Series Applications
Type 309	Used for elevated temperature applications, including 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.
Type 310/S	Corrosion resistant, including 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. Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide and in the food processing industry, they are used in contact with hot acetic and citric acid
Type 330	Combines excellent resistance to carburization and oxidation at temperatures up to 2200 F(1200 C) with high strength.Used in a variety of furnace components as well as in gas turbines, heat exchangers, general heat treating equipment and neutral and cyanide salt pots.
Type 334	titanium- and aluminum-bearing austenitic stainless steel offering superior elevated temperature scaling resistance compared to the conventional chromium-nickel stainless steels. Heated electric heating elements

Advantages of High Temp Stainless Steel

• Oxidation resistance up to 2100°F
• Resistant to carburization and nitriding
• Resistant to thermal Shock
• Good strength at elevated temperature
• Chloride ion stress corrosion cracking resistance
• Superior Creep strength (ability to resist distortion over long term exposure to a high temperature).
