304 Stainless steel introduction

304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; The industry is also known as 18/8 stainless steel, which means containing more than 18% chromium and more than 8% nickel; High temperature resistance 800℃, has the characteristics of good processing performance, high toughness, widely used in industrial and furniture industry and food, medical industry. However, it should be noted that compared with ordinary 304 stainless steel, food-grade 304 stainless steel has a more stringent content index. For example, the international definition of 304 stainless steel is mainly chromium 18%-20% nickel 8%-10%, but food-grade 304 stainless steel is chromium 18% and nickel 8%, allowing a certain range of fluctuations, and limiting the content of various heavy metals. In other words, 304 stainless steel is not necessarily food-grade 304 stainless steel

Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS304 means daily standard production.

304 is a versatile stainless steel, which is widely used in the production of equipment and parts requiring 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 content. 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States.
