Heat Treatment

Laser heat treatment is a technology that allows a localized hardness change to be created. Due to its limited heat input and easy control over the depth of penetration and the width of the treated area, it is widely used in all applications where localized wear is a major problem. 

Laser heat treatment can both harden and soften the surface. Laser hardening allows heat to be applied locally. This allows partial hardening of complex pieces without deformation of the treated part.

Laser softening involves heating the hardened steel to martensite, so the steel structure undergoes a temperature-dependent transformation, allowing the part to be softened.
