Heat treatment of p265gh carbon steel for mechanical processing

What are the characteristics of medium and thick plate, P265GH carbon steel? 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, p265gh carbon steel 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.

The recent improvement in demand is also reflected in p265gh carbon steel social inventory. This year, the growth rate of p265gh carbon steel social inventory has slowed down compared with the same period last year, which indirectly reflects that the demand of p265gh carbon steel this year is better than that of last year. In addition, p265gh carbon steel production, which has set new highs again and again, has slowed down this month, with a slight decline. The decline of p265gh carbon steel production will also alleviate the relationship between supply and demand.

Most common p265gh carbon steel 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 p265gh carbon steel steel plates.

p265gh carbon steel, 13CrMo4-5 steel plate belongs to medium temperature hydrogen vessel steel plate, with Cr content of 0.70% - 1.15%, Mo content of 0.40% to 0.60%. 13CrMo4-5 steel plate is European standard vessel plate, and it is in accordance with EN10028-2. The size, shape, weight and allowable deviation of 13CrMo4-5 steel plate shall comply with EN10029, and the thickness tolerance shall comply with class B deviation in EN10029.
