Discussion on the factors that cause the crack of the spring washer

        Heard a lot of customers come to consult the spring washer, when it comes to the spring washers before they have cracked the case, we analyzed the main reasons for cracking the following points:
1 material itself is not.
2 heat treatment hardness is too high, hardenability is not good.
3 plating hydrogen embrittlement.
The spring washer is widely used in the bearing and non bearing structure of the general mechanical products, which is characterized by low cost and convenient installation. But the spring washer is very loose! Especially in Europe and the United States in the current requirements of high reliability products, the use of very low rate, especially the important load-bearing structure of the connection site has been abandoned for many years. Our country also has some applications in the military, but to improve the stainless steel material. It is said that the steel spring washer in CASC was banned! Also said that it is not safe for two reasons, 1 is "2 ring" is hydrogen embrittlement.
Therefore, users should use different materials according to their own characteristics and post-processing procedures. This can consult the manufacturer of spring washers, I believe their technology can help you solve this problem.
