Increased thermal fatigue resistance & toughness with less distortion than oil quenching.
Maximizing the Heat Treating Process using a 10 Bar Vacuum Furnace and Fluidized Bed Tempering:

To maximize tool life of die cast tooling, hot form tooling, forging or casting tooling the heat treating process must be optimized In order to optimize the mechanical properties inherent in the steel. The 5 most critical factors we closely control are.

  • Controlling the heating rate to control distortion with 12 thermocouples placed in the core and surface of the tools.
  • Maximizing the austenitizing temperature to insure solution of vanadium carbides without causing grain growth.
  • Maximizing the quench rate to increase fatigue strength, hot strength and wear resistance.
  • Allow surface and core to equilize during heating and cooling to prevent distortion (Interrupted Quench above the MS to allow transformation from Austenite to Martensite to occur at same time surface to core reduces stress profile).
  • Tempering in Fluidized Bed Furnaces to insure tools are not under tempered or over tempered. Other batch ovens/ furnaces are slow heating so that by the time the core is up to heat the surface may be over tempered or the core may be under tempered. The Fluidized Bed Furnaces heat uniformly and quickly, much like that of a pot of boiling water.
