65Mn low-alloy round steel must have a high elastic limit and high flexural strength ratio to avoid permanent deformation of spring steel under high load. At the same time also requires good hardenability and low sensitivity to decarbonization, so that the elastic limit greatly reduced; As well as good surface quality, in the hot and cold state of easy processing and good heat treatment technology.
