Grade EH40 – Katalor are suppliers of high quality EH36 structural steel plate to the shipbuilding industry to specification ASTM A131.
The similar shipbuilding steel grade A131 Grade EH40 in steel stand ASTM A131/A131M is mainly used on offshore and oil platform project. Actually A131 Grade EH40 owned the same chemical composition and mechanical property as ABS Grade EH40 shipbuilding steel plates.These two steel grades are in our rolling catalogs.
The high tensile strength in normal shipbuilding steel,LR A131 Grade EH40 ship plate is normally used to build ships which are sailing in the bad surroundings,such as coldest ocean waters and the tough situation.Icebreakers are the main end application for LR A131 Grade EH40 marine steel plate.A131 Grade EH40 can bear the tough ice pieces and low temperature ocean water owing it have to be done impacting test under minus 40 centigrade when rolling.
