On the factors of spring washer cracking caused by force
Release time：2017/1/18 Author：Xinyi spring
When many customers came to inquire about the spring washer, they said that the spring washer they had made before had cracks. We analyzed the main reasons for the cracks as follows:
1. The material itself is not good.
2. The hardness of heat treatment is too high and the hardenability is not good.
3. Hydrogen embrittlement in electroplating.
Spring washer is widely used in the load-bearing and non load-bearing structures of general mechanical products. It is characterized by low cost, easy installation and suitable for frequent assembly and disassembly. But the anti loosing ability of spring washer is very low! Especially in the European and American countries, the adoption rate of high reliability products is very low, especially the important bearing structure connection parts have been abandoned for many years. In our country, there are still some applications in military industry, but the stainless steel materials are improved. It is said that steel spring washer has been banned in CASC for a long time! In other words, it is very unsafe. There are two reasons. One is "rising circle" and the other is hydrogen embrittlement.
Therefore, users should use different materials and post-processing procedures according to their own characteristics. This point can consult the manufacturer of spring washer, I believe their technology can help you solve this problem.
