304 stainless steel coil is a low carbon, molybdenum bearing, austenitic stainless steel coil. Its chemistry features a minimum of 18% chromium and 8% nickel.
These grade stainless steel coils are used for its corrosion resistance to many chemical corrodents, in addition to having good mechanical properties. The corrosion resistance of grade 304 stainless steel makes it ideal for food processing equipment and surgical instruments. It has superior formability and weld ability when compared to other grades of stainless steel.
