Popular S700MC cold forming autobobile steel sheet material hardness

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure

Q345 steel has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability. Q345 steel is used to make mechanical parts, building structures, general metal structural parts for medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures that bear dynamic loads. S700MC cold forming autobobile steel sheet It is used in hot rolled or normalized state. In addition, Q345 steel is also widely used in construction, bridges, vehicles, ships, pressure vessels, etc.

The wear-resistant layer of wear-resistant steel plate is mainly composed of high-carbon and high-chromium alloy. According to the requirements of different users and service conditions, S700MC cold forming autobobile steel sheet, the high-temperature wear-resistant steel plate also contains alloy elements such as Mo, W, V, B, Nb, Ti, etc. The microstructure of the wear-resistant layer is eutectic + M7C3-secondary carbide or complex carbide. It can achieve high wear resistance of normal temperature, high temperature, strong impact, medium impact, and low stress impact.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S700MC cold forming autobobile steel sheet steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

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.
