309 309s 316L Stainless Steel Coil

Stainless steel coils are known for their corrosion resistance and are widely used in numerous applications such as food handling and tableware. Stainless steel does not corrode, rust or get wet as easily as regular steel. However, it is not completely stain-proof in environments with low oxygen, high salinity or poor air circulation.
