Vacuum Heat Treatment

Vacuum heat treatment is a method of heating materials in a vacuum environment to improve their mechanical and physical properties. It is widely used in various industries including aerospace, automotive, medical, and energy.

 Exclusive Features

• Minimal oxidation: The absence of oxygen in the vacuum environment means minimal oxidation of the material being heated. This minimizes the formation of scale and improves the overall surface finish of the material.
• Precise temperature control: Vacuum heat treatment provides precise temperature control, so the material can be heated to a specific temperature and held at that temperature for a specific amount of time. This helps to achieve consistent and repeatable results.
• Reduced distortion: The absence of air in the vacuum environment means that there is no convective cooling, which can reduce distortion and improve the dimensional stability of the material.
• Improved quality: Vacuum heat treatment services can improve the material's mechanical properties such as hardness, strength, and toughness. It can also improve the material's corrosion resistance and reduce residual stresses.

  Applications and Uses

• Aerospace - Vacuum heat treatment is used to improve the performance and durability of critical components such as turbine blades, gears, and landing gear.
• Automotive - This treatment is used to increase the strength and wear resistance of engine components and transmission gears.
• Medical - It is used to sterilize medical instruments and devices, as well as to improve the properties of implants such as orthopedic implants.
• Energy - It helps to improve the performance and durability of components used in power generation, such as gas turbines, steam turbines, and nuclear reactors.

 Advantages of Vacuum Hardening over salt bath hardening

• Hardness uniformity throughout cross section
• Uniform microstructure
• Minimum dimensional distortion
• No oxidation or de-carb on component/ part surface
• Post cleaning not required

  We can process in Vacuum as below type of Grade
