304Stainless SteelIt is a common material found in stainless steel.Density7.93 g/cm³; also known as 18/8 stainless steel in the industry, meaning it contains over 18% chromium and over 8% nickel.NickelWith high-temperature resistance up to 800°C and excellent processing properties.Tensile strengthHigh features, widely used in industrial applications.FurnitureDecorative Industry & FoodIndustry. However, it is important to note that food-grade 304 stainless steel is more strictly defined than the standard 304 stainless steel. For example: The international definition of 304 stainless steel generally includes 18%-20% chromium and 8%-10% nickel, but food-grade 304 stainless steel contains 18% chromium and...Nickel8% fluctuation allowed within a certain range, and the content of various heavy metals is restricted. In other words, 304 stainless steel is not necessarily food-grade 304 stainless steel.
Common marking methods on the market include 06Cr19Ni10.SUS304, where 06Cr19Ni10 generally indicates production in accordance with the national standard, while 304 typically refers toASTM StandardsProduction, SUS 304 indicates Japanese standard production.
304 is a general-purposeStainless SteelIt is widely used in the manufacturing of equipment and components that require excellent overall performance (corrosion resistance and formability). To maintain the inherent properties of stainless steel,Corrosion resistanceSteel must contain over 18% chromium and over 8% nickel content. 304 stainless steel is in accordance with U.S.ASTM StandardsA grade of stainless steel produced.
