    • [News] How to classify surface heat treatment 日期:19-11-06 点击:195 好评:0

      Industrial surface heat treatment processes can be roughly divided into three categories: overall surface heat treatment, surface surface heat treatment and chemical surface heat treatment. Different surface heat treatment techniques are used for the same metal, which can achieve different arrangements and then have different functions. Let's take a look at specific issues to see what three methods are used for surface heat treatment:...
