Which materials are suitable for vacuum heat treatment?

Vacuum heat treatment is suitable for materials that are prone to oxidation or require special protection during heat treatment. Through vacuum heat treatment, the mechanical properties, corrosion resistance and high temperature resistance of the material can be improved, while the chemical composition and microstructure of the material are kept intact. Therefore, this process has been widely used in industries such as aerospace, automobiles, chemicals, energy and electronics. There are many materials suitable for vacuum heat treatment process, mainly including:

1.Alloy steel

Alloy steel is one of the commonly used materials in vacuum heat treatment. Since the vacuum environment can prevent oxidation and decarburization, the chemical composition and microstructure of alloy steel can be maintained, thereby improving its performance. For example, 27SiMn steel contains high alloying elements such as manganese and silicon, which gives it good strength and toughness, and is suitable for the manufacture of various large mechanical parts and engineering structures.

2.Stainless steel

Stainless steel is also very suitable for vacuum heat treatment because the vacuum environment can prevent surface oxidation and maintain its corrosion resistance. In addition, vacuum heat treatment can reduce intergranular corrosion and carbide precipitation that may occur in stainless steel during heat treatment.

3.Tool steel

Tool steel, especially high-speed steel and cold-working die steel, is suitable for vacuum heat treatment. The vacuum environment can prevent oxidation and decarburization during heat treatment, thereby improving the hardness and wear resistance of the tool.

4.Titanium alloys

Titanium alloys are also very suitable for vacuum heat treatment because they are very sensitive to oxidation. The vacuum environment can prevent oxidation and maintain the strength and corrosion resistance of titanium alloys.

5.Nickel-based alloys

Nickel-based alloys, such as the Inconel series of alloys, are usually used in high-temperature environments. They are also very suitable for vacuum heat treatment. The vacuum environment can prevent these alloys from oxidizing at high temperatures, thereby maintaining their high-temperature strength and corrosion resistance.

6.Aluminum alloys

Certain aluminum alloys can also improve their properties through vacuum heat treatment. The vacuum environment can prevent aluminum alloys from oxidizing during heat treatment and improve their mechanical properties.

7.Copper alloys

Copper alloys, especially those used for electrical contacts, can also be improved through vacuum heat treatment to improve their electrical conductivity and heat resistance.
