Low temperature marine grade CCS EH40 steel plate
CCS EH40 steel is lower than CCS FH40 steel in yield and tensile strength. CCS EH40 steel plate is a good material for shipbuilding in deck. CCS EH40 steel plate is in -40 impact test of 34J energy. All of thickness of CCS EH40 steel plate need normalize in delivery station.
Low temperature marine grade CCS EH40 steel plate chemical composition:

Low temperature marine grade CCS EH40 steel plate is used to build ships which are sailing in the bad surroundings, such as coldest ocean waters and the tough situation. Low temperature marine grade CCS EH40 steel plate can bear the tough ice pieces and low temperature ocean water. Each CCS EH40 steel plate has the EN 10204 3.2 Mill Certificate Test proved by CCS classification society.
