How to prevent metal fatigue in Zhuji springs
2023-04-26
Zhuji springs are mainly made of various alloy materials. During the production and use of alloy materials, metal fatigue will inevitably occur. When the metal of the manufactured spring is fatigued, it will have a certain impact on the spring's tensile force and use. From both the production and use perspectives, metal fatigue is unavoidable.
1: During production
When selecting raw materials for metal springs, they need to be heat-treated first. The physical stability of many metal devices will improve after heat treatment, improving their performance. The metal used in spring making can also be heat-treated during production. Heat treatment can be performed together with oxidation treatment.
2: During use
During user operation, if the spring is under a constant load for a long time, its tensile performance will decrease. This is inevitable during spring use. If the spring is under abnormal tensile force, or exceeding the actual tensile force of the spring, the spring will age prematurely, and the metal's fatigue resistance will decrease.
Metal fatigue in springs manifests as the tensile properties being intact momentarily, but the performance significantly deteriorates during use, which is a very troublesome problem. The main method to prevent metal fatigue is to avoid excessive tensile stretching, and to avoid abnormal deformation of the spring during storage, ensuring its overall stability.
