研究了国产仿YUS110及进口SUS316L两类静电除尘器不锈钢星形线材的显微组织、静拉伸性能与疲劳特性.结果表明,两类线材的屈服强度相同,但进口线材的疲劳强度明显高于国产线材;进口线材的疲劳扩展辉纹较国产线材明显细密,且二次裂纹较多较深.分析认为这与两类星形线材的材质及其成形加工造成的形变强化效应有直接关系.
The microstructures, static tensile properties and fatigue properties of stainless steel star wire made from imitation YUS110 and imported SUS316L were studied.The results show that the yield strength of the two types of wire is the same, but the fatigue strength of the imported wire is obviously higher than Domestic wire rod.The imported wire rod is more fine and finer than that of domestic wire rod, and the second crack is more and deeper.The analysis shows that it is directly related to the material of two kinds of star wire rod and the deformation strengthening effect caused by its forming and processing.
