304 material is a representative type of stainless steel with excellent material properties: national standard material, various chemical compositions and mechanical properties meet national standards, dense structure, no pores, no blisters, stable material, superior performance, and strong anti-rust ability. At present, The most versatile stainless steel.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good comprehensive properties (corrosion resistance and formability).
304 stainless steel is a brand of stainless steel produced in accordance with American ASTM standards. 304 is equivalent to GB 0Cr19Ni9 (0Cr18Ni9) stainless steel.
