309 Stainless Steel Coils and 309S Stainless Steel strip
Types 309 Stainless Steel and 309S are austenitic chromium-nickel stainless steels that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. Type 309S Stainless Steel is identical to Type 309 except for a lower carbon content that minimizes carbide precipitation and improves weldability. They are essentially nonmagnetic as annealed and become lightly magnetic when cold worked.
ASTM A167 (309), ASTM A240 (309S)
Typical Applications: furnace parts, heating elements, aircraft and jet engine parts, heat exchangers, sulfite liquor handling equipment, kiln liners, boiler baffles, refinery and chemical processing equipment, and auto exhaust parts
