Why there are quality defects on the surfaces of application of p265gh sheet

P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. application of P265GH sheet, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.

What are the characteristics of medium and thick plate, application of p265gh sheet? 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, application of p265gh sheet 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.

Sulfur is a very harmful element in application of p265gh sheet steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of application of p265gh sheet steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.

The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.
