Vacuum Heat Treatment 40cr Alloy Steel Effect - China

Effect of vacuum heat treatment on GB 40Cr alloy steel Vacuum heat treatment is to heat GB 40Cr alloy steel under a certain vacuum degree, avoiding oxidation and decarburization, obtaining a bright and non-oxidized surface and uniform structure.

The advantages of vacuum heat treatment include:

- Avoiding oxidation and decarburization on the workpiece surface and maintaining the surface quality of the material;

- Effectively removing hydrogen from the metal, preventing hydrogen embrittlement, and improving plasticity, toughness and fatigue strength;

- Partial oxides can be decomposed in a vacuum environment, purifying the metal surface and improving the overall mechanical properties.

After vacuum quenching, the structure of GB 40Cr alloy steel is mainly medium carbon martensite and a small amount of tempered martensite, with fine and uniform structure and excellent performance.

Vacuum degassing technology types

According to different process requirements, vacuum degassing technology is mainly divided into:

- Stream degassing: The molten steel flows in the vacuum chamber, and the gas escapes through the reaction to generate bubbles;

- Circulation degassing: The molten steel circulates in the vacuum to improve the degassing efficiency;

- Ladle degassing: The ladle is placed in a vacuum environment and stirred to enhance the degassing effect.
