How to reduce delamination of p265gh material equivalent

The main function of boron in P265GH material equivalent and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, p265gh material equivalent produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, p265gh material equivalent steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the p265gh material equivalent steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
