304 stainless steel
304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel in the industry.High temperature resistance 800 degrees, with the characteristics of good processing performance, high toughness, widely used in the industrial and furniture decoration industry and food and medical industry.
Common labeling methods on the field include 0Cr18Ni9 and SUS304, among which 06Cr19Ni10 generally represents national standard production, S30408 generally represents ASTM standard production and SUS304 represents daily standard production.
304 is a universal stainless steel, it is widely used in the production of good comprehensive performance (corrosion resistance and molding) of equipment and parts.To maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel.304 stainless steel is a grade of stainless steel produced in accordance with the American standard ASTM.
