304 stainless steel coil manufacturers
304 stainless steel coil is a common material in stainless steel with a density of 7.93 g/cm³. High temperature resistance 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.
Common labeling methods on the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS 304 means Japanese standard production.
304 stainless steel coil is a general-purpose stainless steel product, which is widely used to make equipment and parts that require 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. In 304 stainless steel coil, 304 is a grade of stainless steel produced according to the American ASTM standard.
