NK Grade A steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels,ship body construction.Normally when rolling,Air rolled and Control Rolled is ok for ship plate NK Grade A with the thickness equal and belows 40 Millimeters,and for thickness above 40mm,the heat treatment shall be Normalised or TMCP,these two technical treatment would improve steel strength in yield and tensile points.
Generally before using these ship plates,steel plate pretreatment is necessary.Pre-treatment including shot blasting and painting with shop primer.Some shipyards have its own shot blasting and painting lines,and others have non.Xinsteel set up two pre-treatment lines for shipbuilding steel plate seperately in Shanghai and Tianjin port city for giving customers' one-stop services.For getting more information about NK Grade A steel plate,please be free to contact XINSTEEL now.
