stainless-steel-coil-308 is the most widely used of the austenitic (chromium/nickel) stainless steels. In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. stainless-steel-coil-308 is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

stainless-steel-coil-308 does not readily corrode, rust or stain from water exposure like other steels. Unprotected carbon steel typically rusts when exposed to air and moisture. stainless-steel-coil-308 is used in a wide range of applications including:
Aerospace
Defense
Chemical Processing
Oil and Gas
Electrical Energy
