What are the different types of stainless steel?

316L stainless steel, with an unpolished, mill finish.Main article: Brushed metal Standard mill finishes can be applied to flat rolled stainless steel directly by the rollers and by mechanical abrasives. Steel is first rolled to size and thickness and then annealed to change the properties of the final material. Any oxidation that forms on the surface (scale) is removed by pickling, and a passivation layer is created on the surface. A final finish can then be applied to achieve the desired aesthetic appearance

• No. 0: Hot rolled, annealed, thicker plates
• No. 1: Hot rolled, annealed and passivated
• No. 2D: Cold rolled, annealed, pickled and passivated
• No. 2B: Same as above with additional pass-through highly polished rollers
• No. 2BA: Bright annealed (BA or 2R) same as above then bright annealed under oxygen-free atmospheric conditions
• No. 3: Coarse abrasive finish applied mechanically
• No. 4: Brushed finish
• No. 5: Satin finish
• No. 6: Matte finish
• No. 7: Reflective finish
