How much hardness can the spring be enhanced by shot blasting?
Spring has many uses in industry, and many parts must use spring.Then how to increase the anti-fatigue strength of spring when the spring is used for a long time?
In fact, we can increase the anti-fatigue, then the spring surface produced plastic deformation strengthening layer, and formed a certain thickness; the residual stress formed in higher layer due to enhancement.
The spring surface compressive stress, when the spring loads, it can offset in part of anti-stress, so as to improve the fatigue strength of the spring. residual stress is the main action force.
The use of shot peening technology to increase the fatigue strength of parts will increase the service life of parts, reduce costs and improve efficiency.
