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 S355M steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S355M steel plate during tempering, while tempering determines the performance and life of the workpiece.

Although both HSLA steel plate and carbon steel plate belong to carbon structure and low alloy structure steel, there are some differences. First of all, S355M steel plate, HSLA steel plate and carbon steel plate differ in strength, hardness and use. In terms of strength, the strength of HSLA steel plate is higher than carbon steel plate. In terms of hardness, the hardness of HSLA steel plate is also higher than that of carbon steel plate. And in the scope of use, the advantages of HSLA steel plate are more prominent, so the scope of HSLA steel plate use is more extensive than that of carbon steel plate.
