P265GH is a non alloy quality steel with high temperature performance, executive standard: EN10028-2, number: 1.0425. P265GH plate belongs to medium pressure boiler steel plate. It is a kind of steel plate for pressure vessels in Europe. elongation of p265gh, P265GH plate has good plasticity, toughness, cold bending property and weldability. The equivalent steel grade in China of P265GH is 25MnG.

The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers. At the same time, it keeps pace with the times based on market orientation, continuously expands offline channels, and gradually establishes a complete online E-commerce business management platform. We will always promote our after-sales service to make client satisfied with our goods.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the elongation of p265gh steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of elongation of p265gh seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

The cold working performance of elongation of p265gh and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of elongation of p265gh and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
