The weight of the ship plate can be set according to the weight required by the ship, so that neither the weight of the ship nor the speed of operation will be affected. The price of KF40 ocean engineering steel plate, medium and thick ship plates is determined according to the thickness and quality, which can be combined with the cost of shipbuilding to calculate the price, and then make a choice, so that it will not affect the cost of shipbuilding.
What are the characteristics of medium and thick plate, KF40 ocean engineering steel plate? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, KF40 ocean engineering steel plate is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
Hydrogen (H) is the most harmful element in general steel such as KF40 ocean engineering steel plate. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
