Stainless steel spring washer is widely used in bearing capacity and non-bearing capacity structures of general mechanical products, which has the characteristics of low cost, easy for installation, can frequently installed and disassembled. However, the loose prevention ability of stainless steel spring washer is very low! Especially in the products requiring high reliability in European and American countries, the utilization rate is very low, especially the important bearing structure connecting parts have been abandoned for many years. China still has some applications in the military industry, but it has been changed to stainless steel materials. It is said that CASC has long prohibited the use of stainless steel spring washers! It is also said that it is unsafe for two reasons: one is the expansion ring, and the other is hydrogen embrittlement.
