Development of S460MC special steel for automobiles in China

The carbon S460MC special steel for automobiles content of the pipeline steel is required to be low, and the strength of the pipeline steel is ensured by increasing the manganese content and adding trace elements such as niobium, titanium, vanadium and mo

The carbon S460MC special steel for automobiles content of the pipeline steel is required to be low, and the strength of the pipeline steel is ensured by increasing the manganese content and adding trace elements such as niobium, titanium, vanadium and molybdenum. For pipeline steel, in addition to the required strength and plasticity index, the requirement for toughness index is an outstanding feature, including the impact energy of pipeline steel plate, impact transition temperature and toughness index of welding heat affected zone and welding metal. In addition, there are requirements for strain aging, weldability, stress corrosion and other indicators.

Decarburization in S460MC special steel for automobiles, wear resistant plate is an important reaction in steelmaking process. During the decarburization process, a large number of carbon monoxide bubbles are produced, which makes the molten steel temperature and chemical composition uniform, and can effectively remove the gas and non-metallic inclusions in the molten steel. Because decarburization can play such an important role, in steelmaking, the average carbon content of furnace charge always exceeds the specified carbon content of steel, so as to oxidize the surplus carbon in the oxidation period.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the S460MC special steel for automobiles plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
