P355GH is the European standard pressure vessel plate and sheet. The implementation standard: EN10028-2:2003. shipbuilding use GL-D hull structural steel, EN P355GH steel plate and sheet has good plasticity, toughness, cold bending performance and welding performance, suitable for manufacturing nuclear island steel containment, pressure vessels, equipment structural parts, etc. It is delivered in hot rolled, normalized + tempered condition.
The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the shipbuilding use GL-D hull structural steel, alloy steel is very high, it is not easy to break and can be used for a long time.
Most common shipbuilding use GL-D hull structural 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 shipbuilding use GL-D hull structural steel steel plates.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, shipbuilding use GL-D hull structural steel etc. are common pressure vessel steel grades.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
