45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than SA573 Grade 70 steel for marine engineering quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.
What are the characteristics of medium and thick plate, SA573 Grade 70 steel for marine engineering? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, SA573 Grade 70 steel for marine engineering is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Most common SA573 Grade 70 steel for marine engineering steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled SA573 Grade 70 steel for marine engineering steel plates.
