During the laser marking process called annealing, no material is taken away, which means there is no ablation. During the laser marking service, there is no tangible mark on stainless steel and other metals; however, a color change occurs through heating up the metal.
Because material is not moved or displaced in the annealing process, that eliminates the possibility of surface grooves, which prevents the potential for bacteria to grow or for any type of corrosion to occur.
