304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; it is also called 18/8 stainless steel in the industry, meaning it contains more than 18% chromium and more than 8% nickel; high temperature resistance of 800 ℃, with good processing performance , With the characteristics of high toughness, it is widely used in industry and furniture decoration industry and food and medical industry. However, it should be noted that food-grade 304 stainless steel has stricter content indicators than ordinary 304 stainless steel.
For example: the international definition of 304 stainless steel is basically 18%-20% of chromium and 8%-10% of nickel, but food-grade 304 stainless steel is 18% of chromium and 8% of nickel, which is allowed to fluctuate within a certain range, and Limit the content of various heavy metals.
