Laser Hardening

Laser hardening offers many advantages over conventional heat treatment processes. Because the laser heat treatment is local, tools do not have to be placed in dedicated furnaces and their preparation also only needs to be local. In many applications, this localized treatment and minimal overall heat input results in reduced or total elimination of tool distortion. The typical rapid quench rates produce a highly desired, fine microstructure. Laser hardening has high throughput, high reproducibility and results in superb product quality, which makes it an economical choice.
