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, which means that it contains more than 18% chromium and more than 8% nickel; high temperature resistance of 800 ℃, good processing performance , High toughness, widely used in industry 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 stricter content index. For example, the international definition of 304 stainless steel is basically 18%-20% chromium, 8%-10% nickel, but food-grade 304 stainless steel contains 18% chromium and 8% nickel, allowing fluctuations within a certain range, and 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, among which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS 304 means Japanese standard production.
304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard
