Stainless Steel: About SUS 304 .
304 Stainless steel is one of the most common grades of stainless steel used for food preparation and dining, It is an austenite steel is non-magnetic,contains 18-20% chromium and 8-10.50% nickel, and lesser quantities of some other elements,The chromium binds oxygen to the surface of the product to protect the iron from oxidation (rust). Nickel also enhances the corrosion resistance of stainless steel. Therefore, the higher the nickel content, the more resistant the stainless steel is to corrosion,For example, 18/10 stainless steel is comprised of 18% chromium and 10% nickel.
