Surface decarburization is one of the important processes in hot-rolled plate production.Decarburizing characteristics of 50CrV4 steel and its effect on hardenability of steel at 650~1 100℃ were investigated in the laboratory.According to the diffusion theory,the test data were studied through regression analysis.The research shows that the decarburized depth increases with the increase of temperature or holding time,and the depth is proportional to the extraction of the holding time.There is a minimum value in decarburized depth appearing at 1 000~1 100℃.The hardness of the steel decreases with the increase of the decarburized depth.
