304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³. 304 stainless steel is also called 18/8 stainless steel, which means it contains more than 18% chromium and more than 8% nickel.
304 stainless steel has a high temperature resistance of 800 ° C. 304 stainless steel has the characteristics of good processing performance and high toughness. 304 stainless steel is widely used in industry and furniture decoration industry and food medical industry.
Compared with ordinary 304 stainless steel, food grade 304 stainless steel has stricter content indicators. For example, the international definition of 304 stainless steel is that it mainly contains 18%-20% chromium and 8%-10% nickel, but food-grade 304 stainless steel contains 18% chromium and 8% nickel, which allows fluctuations within a certain range and limits content of various heavy metals. That is to say, 304 stainless steel is not necessarily food grade 304 stainless steel.
304 stainless steel is a versatile stainless steel, which is widely used in the production of equipment and parts that require good overall performance (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. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
