After heat treatment and cold drawing, it has high strength and certain flexibility and plasticity.Under the same surface condition and full quenching, the fatigue limit is the same as the color alloy spring.It is mainly used for spring of smaller size, such as pressure regulating spring, force measuring spring, round and square spiral spring or drawn into steel wire for spring of small machine.

  1. General Details

    65Mn 1065 High Carbon Spring Steel, Alloy Steel

    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.
