304 stainless steel is a common material in stainless steel with a density of 7.93g/cm3. It is also called 18/8 stainless steel in the industry. It is resistant to high temperature of 800℃, has the characteristics of good processing performance and high toughness, and is widely used in industry, furniture decoration industry and food and medical industry.
Among the common marking methods on the market are 06Cr19Ni10 and SUS304. Among them, 06Cr19Ni10 generally represents national standard production, 304 generally represents ASTM standard production, and SUS 304 represents Japanese standard production.
304 is a versatile stainless steel, which is widely used in the production of equipment and parts that require good overall performance (corrosion resistance and formability). In order 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 ASTM standard.
