Talking about the factors that cause the crack of the spring washer to cause the crack
When I heard many customers came to consult the spring washers, they said that the spring washers they had had had cracked before. We analyzed the main reasons that led to the cracking:
1. The material itself does not work.
2. The heat treatment hardness is too high and the hardenability is not good.
3. Electroplating hydrogen embrittlement.
Spring washers are widely used in the bearing and non-bearing structures of general mechanical products. They are characterized by low cost and easy installation, and are suitable for parts with frequent assembly and disassembly. However, the spring washer has a low anti-loose ability! Especially in the current European and American countries, the adoption rate of highly reliable products is extremely low, especially the important bearing structure connection parts have long been abandoned for many years. Our country has some applications in military industry, but it is improved to stainless steel. It is said that steel spring washers have long been banned in CASC! It is also said to be very unsafe, for two reasons 1 is "up circle" 2 is hydrogen embrittlement.
Therefore, users should use different materials and post-processing procedures according to their own use characteristics. You can consult the manufacturer of spring washers and believe that their technology can help you solve this problem.
