This guide covers the finishing options you&#8217;re most likely to encounter when specifying stainless steel parts: passivation, polishing, plating, and decorative coloring. Why Stainless Steel Needs Passivation Stainless steel resists corrosion because chromium in the alloy \u2014 typically 17\u201320% \u2014 reacts with oxygen to form a thin, stable chromium oxide layer on the surface. This passive layer is what &#8220;passivation&#8221; refers to, and it&#8217;s what actually protects the part, not the base metal itself. Machining, [&hellip;]"}
