FIELD: vacuum carburizing.
SUBSTANCE: invention relates to a method for vacuum carburizing steel parts with threaded holes while protecting the internal thread. Reusable copper plugs are installed in the threaded holes of steel parts along the thread. Then vacuum carburizing of said steel parts and dismantling of said plugs is carried out.
EFFECT: reduction of the duration of the technological process of manufacturing parts hardened by carburizing due to the exclusion of mechanical processing after carburizing.
