Stainless Steel: All About Food Grade 304, 18/8 and 18/10 stainless steel cr steels

For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel. 304 grade stainless steel is also comprised of no more than 0.8% carbon and at least 50% iron. 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.The Characteristics of Austenitic Stainless SteelAustenitic steels are non-magnetic stainless steels that contain high levels of chromium and nickel and low levels of carbon. Known for their formability and resistance to corrosion, austenitic steels are the most widely used grade of stainless steel.The Difference Between 304 and 316 Stainless Steel | Metal stainless steel cr steelsMar 22, 2018 · Additionally, many austenitic stainless steels are weldable and formable.
