Product Introduction

304 is a versatile stainless steel widely used in equipment and components requiring excellent overall performance (corrosion resistance and formability). To maintain stainless steel's inherent corrosion resistance, the steel contains at least 18% chromium and at least 8% nickel. 304 stainless steel is a grade produced in accordance with US ASTM standards.

Common marking methods on the market include 06Cr19Ni10 and SUS304, among which 06Cr19Ni10 generally indicates production according to national standards, 304 generally indicates production according to ASTM standards, and SUS 304 indicates production according to Japanese standards.
