A precision, high volume steel component was locally transformation hardened with a high power continuous wave Nd:YAG laser. No organic coating was required to achieve efficient energy coupling to the material. The processed component had high hardness and low distortion. The process cycle time was quite appropriate for the production volumes considered.
