304 stainless steel plate

304 is a versatile stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States.
