CCS shipbuilding steel plate require good low temperature toughness and good welding performance. The production high-strength shipbuilding steel plate needs to be normalized by means of controlled rolling and controlled cooling or heat treatment processes with more complete equipment. At the same time, the internal steel purity of the supplied billets is required to be high, especially the content of S, P, N, 0 and H in the steel should be strictly controlled.
CCS shipbuilding steel plate including the following grades
CCS Grade AH40 steel is the impact force subjected to 0 °C
CCS Grade DH40 steel impact force at -20 °C
CCS Grade EH40 steel impact force at -40 °C
CCS Grade FH40 steel impact force at -60 °C
