304 stainless steel pipe

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; High temperature resistance of 800 ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry. However, it should be noted that the content index of food grade 304 stainless steel is more strict than that of ordinary 304 stainless steel. For example, the international definition of 304 stainless steel is basically that it mainly contains 18% - 20% chromium and 8% - 10% nickel, but food grade 304 stainless steel contains 18% chromium and 8% nickel, which allows fluctuations within a certain range and limits the content of various heavy metals. In other words, 304 stainless steel is not necessarily food grade 304 stainless steel

Common marking methods in the market include 06cr19ni10 and SUS304, of which 06cr19ni10 generally refers to national standard production, 304 generally refers to ASTM standard production, and SUS 304 refers to Japanese standard production.

304 is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance (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 according to American ASTM standards.
