KD36 hull ship structural steel plate, S460G2+M is a kind of European standard steel plate, which belongs to weldable structural steel for fixed coastal structure. Its delivery state is thermo mechanical rolling, and the impact test is -40 degrees. The 2 after G represents the relevant number of steel grade characteristics, and the latter + M means thermo mechanical rolling.
For the hot pressing of the head, the initial temperature is 930-950℃, and the final pressing temperature (that is, the temperature at the time of demolding) should not be lower than 850℃. If KD36 hull ship structural steel plate the temperature drops to close to 850℃, it cannot be pressed. It should be quickly returned to the furnace and heated before pressing.
The difference between KD36 hull ship structural steel plate, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
