304 is a general-purpose stainless steel, which is widely used in the production of equipment and machine parts requiring a good combination of properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium, more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
