304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm ³; Also known as 18/8 stainless steel in the industry, it means containing over 18% chromium and over 8% nickel; High temperature resistance of 800 ℃, with good processing performance and high toughness, widely used in industrial and furniture decoration industries, as well as food and medical industries. However, it should be noted that food grade 304 stainless steel has stricter content indicators compared to ordinary 304 stainless steel. For example, internationally, the basic definition of 304 stainless steel is that it mainly contains 18% -20% chromium and 8% -10% nickel, while food grade 304 stainless steel contains 18% chromium and 8% nickel, allowing for fluctuations within a certain range and limiting the content of various heavy metals. In other words, 304 stainless steel does not necessarily mean it is food grade 304 stainless steel
Common labeling methods in the market include 06Cr19Ni10 and SUS304, where 06Cr19Ni10 generally represents national standard production, 304 generally represents ASTM standard production, and SUS304 represents Japanese standard production.
304 is a versatile stainless steel widely used in the production of equipment and components that require good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, it 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.
SUS304 is a Japanese label number, equivalent to the domestic label 0Cr18Ni9. SUS304 WPB springs are made of stainless steel wire, and WPB refers to its strength level, including WPA, WPB, and WPC. It can be classified into matte, glossy, nickel plated matte, and nickel plated glossy.
