Annealing colors marking makes use of the structural change that occurs on steel and titan at high temperatures. A well-known example of annealing colors are stainless steel exhaust pipe parts, which turn dark at high operating temperatures. With the laser, this effect can be achieved even on a very small area thanks to its high thermal impact. The metal changes to a dark color and an excellent contrast is achieved.

The marking speed that can be reached depends to a great extent on the average power and the laser beam diameter. This technique can be applied to ferrous metals. Non-ferrous metals do not behave in the same way.
