304 stainless steel

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 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 the Limit the content of various heavy metals. In other words, 304 stainless steel is not necessarily food grade 304 stainless steel.

Common labeling methods on the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS 304 means Japanese standard production.

304 is general-purpose stainless steel that is widely used to make equipment and parts that require a good combination of properties (corrosion resistance and formability). 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.
