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 it contains more than 18% chromium and more than 8% nickel; it is resistant to high temperatures of 800°C and has processability Good, high toughness characteristics, widely used in industrial and furniture decoration industries and food and medical industries. However, it should be noted that 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 is allowed to fluctuate 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 marking methods on the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally represents national standard production, 304 generally represents ASTM standard production, and SUS304 represents Japanese standard production.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good comprehensive properties (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 brand of stainless steel produced in accordance with American ASTM standards.
