Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,AH40 steel plate is mainly used for shipbuilding and oil platform, the shipbuilding grade AH40 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons. Shipbuilding grade AH40 is the high tensile strength steel, AH40 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.40% (thickness ≤ 50mm). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
