Minimal Distortion, Bright Results

As in annealing, brazing, and stress relieving, vacuum metal processing of tooling and high strength steel can give you an advantage over conventional hardening and tempering.  Vacuum hardening prevents high temperature oxidation and decarburization, while gas quenching from vacuum minimizes distortion over traditional oil quenching.  Vacuum tempering keeps parts bright and clean with no temper scale.
