English
Integral heat treatments such as annealing, normalizing, hardening, and tempering. Conformal heat treatment is the combination of pressure processing, deformation, and heat treatment to improve the strength and toughness of the workpiece. Vacuum heat treatment, carried out in a negative-pressure atmosphere or vacuum, is used to maintain the surface of the workpiece bright and clean. Ageing treatment to eliminate the size and shape changes of precision gauges or molds that occur over long-term use. Surface quenching, whereby the surface layer is hardened, while the core remains unchanged.
