Domestic lr/ah36 ship building steel plate prices drop slightly

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in lr/AH36 ship building steel plate etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

The economical duplex stainless steel is used for various structural components such as cable tray, pipe support device and other secondary components in non high temperature environment. Its advantages are long life, less maintenance and light weight. Lightweight is the key to control the construction cost of the platform. Duplex stainless steel makes offshore oil and gas platform lighter and safer.

Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary lr/ah36 ship building steel plate products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.

Last week (November 7~November 13), the price of imported iron ore increased overall. The price of external disks rose rapidly, and fell slightly towards the end of last week, and the spot price of the port increased. The price increase of iron ore is more driven by the price increase in the steel market. From the perspective of iron ore fundamentals, iron ore inventories in major ports continue to rise rapidly, steel mills are generally willing to purchase, and it is difficult for prices to continue to rise.
