304 is a versatile stainless steel, which is widely used in the manufacture of equipment and components requiring good comprehensive properties (corrosion resistance and formability). 304 stainless steel is a brand of stainless steel produced according to American ASTM standard. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China. 304 contains 19% chromium and 9% nickel. 304 is the most widely used stainless steel, heat-resistant steel, practical steel, Huaye steel. For food production equipment, general chemical equipment, nuclear energy and so on.

 

In order to maintain the inherent corrosion resistance of stainless steel, a high alloy steel which can resist corrosion in air or chemical corrosion medium must contain more than 12% chromium.
