摘要
Abstract
The causes of cracks in stainless steel pump head were analyzed by chemical composition analysis,mechanical property test,macroscopic test and metallographic test.The results show that the fatigue strength of the pump head is insufficient due to its low tensile strength and coarse grain size.Under the action of cross-loading stress,the material is easy to crack due to fatigue.关键词
