Abstract:  
Peening automotive chassis springs with cut- wire shot has improved quality and lowered costs, says Miller in this article, based on a paper he presented at a recent meeting of the SAE Shot Peening Division, of the SAE Iron & Steel Technical Committee. He notes that peening has been a costly and comparatively uncontrollable operation because of excessive peening shot usage, short shot life, formation of grit which prevents control and makes for high maintenance costs, and lack of size uniformity and quality of shot as furnished. Results of tests with shot made from hard drawn wire, detailed here by Miller, indicate that the new material overcomes these drawbacks.
