Low welding crack sensitivity high-strength steel plate, today mainly introduces Q620CF, with three grades C, D, E. The grades of low-welding crack sensitivity high-strength steel plate: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD , Q550CFE, Q620CFC, Q620CFD, Q620CFE, Q690CFC, Q690CFD, Q690CFE, EN steel grade S450J0 material, Q800CFE. It is mainly used for the production of hydropower penstocks, construction machinery, railway vehicles, bridges, high-rise and large-span buildings that require high weldability.

The main applications of normalizing are as follows:① For low carbon steel, EN steel grade S450J0 material. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

EN10083-3 42CrMo4 steel plate is a common chromium-molybdenum steel that usually used after quenched and tempered. EN steel grade S450J0 material, EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness. EN10083-3 42CrMo4 steel plate has better performance than 34CrMo4 steel due to the carbon and chromium content is higher.

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
