摘要： A device for providing selective heat treatment on a metal sheet comprising boron steel is provided. The device comprises a laser source for emitting a laser beam onto the metal sheet to provide a selective heat treatment thereon, wherein a defined heat treated grid pattern is formed on the metal sheet by the selective heat treatment. The device further comprises a control unit arranged to control the operation of the laser source for providing the defined heat treated pattern onto the metal sheet; and control the case hardness depth of the defined heat treated pattern based on a temperature parameter and a holding time parameter associated with the operation of the laser source. A method for performing controlling the case hardness depth of a selectively heat treated metal sheet of boron steel is also provided.
