Heat Treatment
Cryogenic

PROCESS DESCRIPTION

The Cryogenic treatment is a process that consists of introducing the parts in temperatures between -70ºC and -150ºC in order to cross the Mf point (end of martensitic formation) to ensure that the retained austenite generated in the tempering is transformed into martensite. In this way, hardness is increased while maintaining good toughness because austenite is a soft phase of steel.

APLICATIONS

Medium and high alloy steels that have been previously carburized and quenched and in which have been produced a significant retained austenite contents.

PROCESS DETAILS

  • Heat treatments performed in vacuum furnaces and therefore suitable for its application in finished parts.
  • Minimum distortion.
  • Control and monitoring of process temperatures during all the heat treatment.
  • Register of all parameters and process controls, traceable with Customer registers.
