CCS EH40 Shipbuilding Plate
EH40 ship steel plate is -40 degrees impact high-level ship plate, the implementation of classification society standards, high-strength ship plate is divided into four quality levels, specifically AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, EH40 and low alloy steel plate is the same, the Z performance of the plate is mainly required to sulfur content and elongation after break. and elongation after break, the higher the requirement the lower the sulfur content, Z performance is the thickness direction performance of the steel plate, steel plate anti-laminar tear test Z performance is an important technical requirement in the requirements of the steel plate, applicable to the thickness of 15mm-300mm between the thickness of the thick steel plate thickness direction of the resistance to pressure to provide a guarantee.

2. The Figure in the ( ) means the sampling volume to do the impact test, the unit is Ton.(-) means without impact test.
EH40 ship plate application
EH40 shipbuilding plates within the more alloying elements, strict requirements are often used in shipbuilding, sea construction platforms, port machinery, marine parts manufacturing, marine pipeline deck machinery, and so on.
EH40 ship building steel plate in addition to the use of shipbuilding and ship repair, but also can be used instead of mining machinery, construction machinery, lifting equipment, large steel structures, offshore oil platforms, harbor platforms and so on.
