LR A131 Grade EH36,A131-EH36 high strength steel plate
Source:Xin Steel Industry Date:2013/07/23
The high tensile strength in normal shipbuilding steel,LR A131 Grade EH36 ship plate is normally used to build ships which are sailing in the bad surroudings,such as coldest ocean waters and the tough situiation.Icebreakers are the main end application for LR A131 Grade EH36 marine steel plate.A131 Grade EH36 can bear the tough ice pieces and low temperature ocean water owing it have to be done impacting test under minus 40 centigree when rolling.
