What is 304 stainless steel?

304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; The industry is also called 18/8 stainless steel, which means containing more than 18% chromium and more than 8% nickel; High temperature resistance 800℃, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry. However, it should be noted that compared with ordinary 304 stainless steel, food-grade 304 stainless steel has a more stringent content index. For example, the international definition of 304 stainless steel is mainly chromium 18%-20% nickel 8%-10%, but food-grade 304 stainless steel is chromium 18% and nickel 8%, allowing a certain range of fluctuations, and limiting the content of various heavy metals.
