In terms of steel for offshore platforms, steel also plays an important supporting role. Because the offshore platform is immersed in sea water for a long time, it also needs to withstand the test of various harsh sea conditions such as storms, waves, glaciers, etc. Therefore, the steel NV E40 hull structural steel plates for offshore platforms requires not only high strength, but also good corrosion resistance, low temperature toughness and resistance, lamellar tearing performance, etc.
Superior process production line advantage sdf: The company has focused on weathering steel NV E40 hull structural steel plates, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.
The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.
The main function of boron in NV E40 hull structural steel plates 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.
