Abstract: By means of the hardness test,wear experiment and microstructure observation of the super narrow 2Cr13 steel strip during continuous heat treatment under different tension.The influence of the tension on the wear resistance of super narrow 2Cr13 steel strip was investigated.The result shows that when the tension loaded on the steel strip not exceed 98 N(the width reduction rate < 1.8%),the wear resistance of the sample does not change.While the tension load on the steel strip is higher than 98 N(the width reduction rate > 1.8%),the wear resistance of the sample become worse as the tension raise.
