Compared with 150mm GL-FH 40 hull structural steel, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
Since March 20, 2020, the export tax rebate rate of some steel products in China has been increased. According to statistics, the export volume of 150mm GL-FH 40 hull structural steel and so on steel products within the adjustment scope in 2019 is 18.888 million tons, accounting for 29.4% of China's total steel exports; the export volume is 14.05 billion US dollars, accounting for 26.1% of the total steel exports. The adjustment will be conducive to the export of some steel products in China and reduce the purchase cost of foreign customers.
Non-destructive flaw detection of steel plates is a test method for inspecting the 150mm GL-FH 40 hull structural steel surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used 150mm GL-FH 40 hull structural steel steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
