304 stainless steel is the most common austenitic stainless grade worldwide, containing 18% chromium and 8% nickel. It offers excellent corrosion resistance, good formability, and outstanding weldability. In China it is designated 06Cr19Ni10 (GB/T 20878), in Japan SUS304 (JIS), and in Europe 1.4301 (EN). Available in plate, coil, sheet, bar, and pipe with surface finishes including 2B, BA, No.4, HL, and 8K mirror.
