Type 304 Stainless Steel: Arc-Melted, AOD-Refined and Cast into Blooms and Slabs
Stainless steel is steel with at least 10.5 % chromium, which forms a thin protective oxide film; type 304 (18/8, 1912) adds nickel. Melt steel with ferrochrome and ferronickel in an electric arc furnace, take the carbon out with argon and oxygen in an AOD converter, and cast it continuously into blooms for bars and wire or slabs for sheet.
