The highest tensile strength in normal shipbuilding steel,NK Grade EH40 ship plate is nromally 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 NK Grade EH40 marine steel plate.NK Grade EH40 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.
One of our customer from Canada ordered two heavy shipbuilding steel plates NK Grade EH40 to repair their naval icebreaker which used in north pole as a trial order.When the plates used in their repaired work,their engineers pleased to order us five hundred tons NK Grade EH40 and NK Grade FH32 ship steel plate because of our high quality steel peoperty.
