Mechanical Characteristics Of Stainless Steel Spring Washers

Stainless steel spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products, and have the characteristics of low cost, convenient installation, and frequent installation and disassembly. But the anti-loosening ability of stainless steel spring washers is very low! Especially in the products that require high reliability in European and American countries, the utilization rate is extremely low, especially the important bearing structure connecting parts have been abandoned for many years. my country still has some applications in military industry, but it has been improved to stainless steel. It is said that CASC has long banned the use of steel spring washers! It is also said to be very unsafe for two reasons: one is ring expansion and the other is hydrogen embrittlement.

Stainless steel spring washers in the screw industry are often called spring washers. Its materials are stainless steel and carbon steel, and carbon steel is iron. Commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14, M16. The national standard GB/T94.1-87 stainless steel spring washer, the standard specification is 2-48mm standard stainless steel spring washer.
