Vacuum Heat Treating

Vacuum Heat Treating

Our advanced vacuum heat treating capabilities allow for precise control over the heat treatment environment, eliminating contamination and ensuring high-quality results for critical aerospace components. This process enhances the mechanical properties of metals, such as improving hardness, strength, and resistance to wear and corrosion, making it ideal for aerospace applications.

Benefits of Vacuum Heat Treating:

  • Oxidation-Free Results: Perfect for components that require clean, scale-free surfaces.
  • Material Consistency: Precise control of temperature and atmosphere for uniform results.
  • Enhanced Mechanical Properties: Improved fatigue resistance, toughness, and performance at extreme temperatures.

 

 

Subzero treating is performed at temperatures of -120°F in our cold chambers to convert microstructure of retained austenite to martensite or increase wear life of tool steels.
