Scope

This standard specifies the vacuum low-pressure carburizing high-pressure air paint heat treatment equipment with a double-chamber structure and an absolute pressure of high-pressure air paint up to 2 MPa, as well as technical requirements for its process, quality control and inspection, safety, sanitation, and environmental protection. This standard is applicable to the heat treatment process of vacuum low-pressure carburizing and high-pressure gas for steel parts using hydrocarbon-based gases such as acetylene, propane, etc. as carburizing medium.
