Esterer Gießerei - Hardening


Hardening is a casting technique where we deliberately change the mechanic characteristics of a cast material with the aid of heat treatment. Normally, the goal is to increase the mechanic resistance of a casting.

At hardening we distinguish between transformation hardening, e.g. through quenching and age hardening.

For hardening of steel and iron alloys the process of quench hardening is used. If after hardening the process of tempering is carried out, we talk of annealing.
