Posted by abyihui on July 10th, 2019

Some of the bolts we produce are not hard due to the hardness, so some of them need to be heat treated, that is, the bolts of the original color are hardened. This is due to the fact that when the bolt is driven into the product material, the hardness of the bolt may not cause many problems. Therefore, some materials that are relatively hard must require bolts for heat treatment. However, if the screw is not heat treated, or in the process of heat treatment of the screw, the treatment is not good. What are the undesirable phenomena at this time, and what are the bad problems?
What are the problems with the heat treatment of bolts? Next, the professional Bolt Factory, Haiyan Yihui Hardware Technology Co., Ltd., combined with the situation of the previous customers' screw heat treatment. A brief analysis of the experience shows that the bolt heat treatment is not good, two situations will occur. One is the bolt thread thread slippery, and the other is that the bolt is broken directly from the head and the thread. There are two aspects to this poor heat treatment. One aspect is that the bolt heat treatment does not reach the required hardness target, and on the other hand, the hardness of the bolt heat treatment exceeds the specified hardness target. That is, the bolts are too hard. If the bolt is too hard, it will simply break.
