Oxygen is a harmful element in LR FH40 shipbuilding steel plates steel. With the increase of oxygen content, the strength of LR FH40 shipbuilding steel plates steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of LR FH40 shipbuilding steel plates steel.
How to predict the price trend of medium and heavy plate, LR FH40 shipbuilding steel plates? First, the output of steel plate. The future annual plan of the major steel mills can be learned timely through the official website. Second, market demand forecast. Third, overall data of the global steel, judgment and rectification of foreign political trade, such as tariff. Of course, we should also consider the transportation cost and other factors, which will also affect the price of medium and heavy plate, LR FH40 shipbuilding steel plates.
In recent years, in line with the development trend of iron and LR FH40 shipbuilding steel plates steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which LR FH40 shipbuilding steel plates are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Training is one of the important factors in the construction of corporate culture.
