The shot is screened to size, then heat treated and air quenched in two separate operations to achieve proper microstructure and hardness.

This superior heat-treat and air quench process :

  • Eliminates potential exposure to non-visible contaminants that may be present in water quenching processes
  • Produces superior particle integrity with minimal stress crack
