STAINLESS STEEL 300 SERIES

The 300 series stainless steels are classified as austenitic and are hardenable only by cold working methods. These grades of stainless have approximately 18% to 30% chromium and 6% to 20% nickel as their major alloying additions. This series of stainless steel alloys are known to resist corrosion while maintaining their strength at high temperatures.

While the 304 grade is the most widely used alloy of all stainless steels, the 300 series grades are inventoried in stainless steel plate, sheet, bar, pipe, tube and fittings and much more. 300 Series also resist etching and cracking better than other grades of stainless steel.

Bhavik Steel & Alloys inventories a wide range of stainless steel heat resistant grades, including 309, 309S, 309H, 310, 310S, 310H, and 330. High temperature stainless grades are stocked in stainless steel plate, sheet, bar and tubular forms.

applications

301– High strength grade, with resistance to atmosphere corrosion. Its bright, attractive surface makes it an excellent choice for decorative structural applications.
304– Used for a wide variety of home and commercial applications. One of the most. familiar & frequently used alloys in the stainless steel family. Common applications include Sanitary, Cryogenic, and Pressure-containing applications, Home and commercial appliances, Tank structural parts and processing equipment.
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.
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.
316– Used for elevated temperature applications, including handling hot organic and fatty acids, boat rails and hardware and facades of buildings near the ocean.
317– More resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels. These alloys offer high tensile strength at elevated temperature.
321– A stabilized stainless steel which offers excellent resistance to corrosion following exposure to temperature between 800-1500 Deg F. Applications include Boiler and Pressure Vessels.
347– Stabilized stainless steel which offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation rages from 800 to 1500 Deg F. Radiant heaters, Aerospace components and Oil Refining equipment.
