Stainless steel 303 is an austenitic stainless steel that contains 18% chromium and 8% nickel. It is non-magnetic and has good corrosion resistance due to the addition of sulfur to the composition. This type of stainless steel is commonly used in the production of screws, bolts, and other fasteners due to its ease of machining. It can also be found in the production of various forms of wire and tubing.
