How to control the depth of decarbonization layer under the protective atmosphere of conventional materials

The method for control that depth of the protective atmosphere decarburization layer of the material comprise the following steps: controlling the temperature and time of heat treatment, adopt protective atmosphere heat treatment, and selecting a suitable metal material.

1, and control the heat treatment temperature and time. Avoid too high temperature and too long time to reduce the occurrence of surface decarburization.

2. Heat treatment in protective atmosphere. Metal materials are heated in a protective atmosphere to prevent oxygen from reacting with carbon on the metal surface.

3. Choose a suitable metal material. Try to choose materials with low carbon content to reduce the depth of decarburization layer on the surface.
