| Abstract: | Synopsis In order to meet the stringent requirements of high fatigue life of the valve spring for oxide inclusions, a technique of harmless inclusions has been developed abroad according to the theory of inclusion morphology control. The ultra clean valve spring steel manufactured using this technique gets rid of the deleterious effect of oxide on material fatigue properties through thinning and softening oxide inclusion, thus raising the fatigue limit and life of the valve spring. |
