Stainless Steel Machinery Parts manufacturers tell you that scratches and other rough surfaces must be mechanically cleaned in order to prevent the build-up of process lubricants or products and/or dirt, typically with a stainless steel special polisher. If the stainless steel is heated to a certain high temperature in the air during welding or grinding, the chromium oxide thermal tempering color will appear on both sides of the weld, the lower surface, and the bottom of the weld.

Stainless Steel Machinery Parts manufacturers tell you that heat tempered color is thinner than oxide protective film and is clearly visible. Color depends on the thickness and can be found in iridescent, blue, violet to yellowish, and brown. Thicker oxides are generally black. It is caused by staying at high temperatures or for prolonged periods of time at higher temperatures.
Stainless Steel Machinery Parts manufacturers tell you that when any of these oxide layers are present, the chromium content on the metal surface is reduced, resulting in reduced corrosion resistance in these areas. In this case, not only the hot-tempered color and other oxide layers should be removed, but also the chromium-depleted metal layer beneath them should be cleaned.
The above information is the Stainless Steel Machinery Parts manufacturer's introduction and analysis of the scratches that may occur when making mechanical parts, hope it helps you.
