Steel Tempering Colour Chart West Yorkshire Steel Co Ltd

These are always shades of red, orange, and yellow because they're above the critical (or transformation) temperature that makes the metal glow from the heat. Forging colors are as follows: What causes the change in color? When a piece of steel is tempered, a thin oxide layer forms on the surface of the metal.
