Carburizing and anti-carburizing and heat treatment method using the same means of preventing metal parts

摘要

The present invention relates to a carbonitriding prevention means for preventing local carburizing, carbonitriding, or nitriding of a heat treated metal component, comprising: a sealing cap member (100); and a soft caulking member (200). Accordingly, unnecessary processes can be significantly reduced, thereby improving productivity, increasing production efficiency, and reducing producing costs.
