The main advantage of hardened steel washers is their high hardness. Due to their high hardness, hardened steel washers reduce wear and prolong service life in connection situations where there is frequent friction and relative motion. In the connection of precision equipment such as machine tools, this abrasion resistance ensures the precision of the equipment and reduces the loss of precision and the number of repairs caused by wear. In application scenarios subject to pressure and friction, such as in highly loaded mechanical transmissions or frequently disassembled and installed joints, it effectively resists wear.
The hardened steel washer's hardness and strength have been significantly increased by a special treatment. This enables them to withstand enormous axial and shear forces, for example in critical connection areas of large construction machinery, such as the connection between the crane's lifting arm and the base, where the hardened steel washer can easily cope with the enormous pressures generated by the lifting of heavy loads. This also ensures that the connection structure is stable and there will be no crushing or deformation of the washer, thus guaranteeing the safe operation of the whole equipment.
