The correct choice of billet type, section shape, size and weight are of great significance to S420ML material price steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The S420ML material price rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S420ML material price.
