The correct choice of billet type, section shape, size and weight are of great significance to Q345B carbon steel plate sheet 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 Q345B carbon steel plate sheet rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be 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 carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, Q345B carbon steel plate sheet, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
