Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched q235 q345 carbon steel i beam increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of q235 q345 carbon steel i beam during tempering, while tempering determines the performance and life of the workpiece.
