This article investigates the effect of various degrees of plastic deformation introduced by cold rolling at ambient temperature on the tensile properties of 301 stainless steel containing 0.8% Mo.The results indicate that the formation of strain-induced martensite evidently leads to a significant strengthening of the steel.The tensile and yield strengths as well as hardness increase linearly with the increase of cold rolling reduction.After 52%rolling reduction,the amount of martensite is about 75%, and the tensile strength is elevated to be about 1700 MPa.The addition of 0.8%Mo has a slight effect on tensile and yield strengths,but the plasticity is not decreased.
