FH40 steel plate

FH40 steel plate

The steel for shipbuilding and oil platform---FH40 shipbuilding steel, is the high tensile strength steel.
It is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.This kind of steel can be used in the manufacture of the ocean ship's hull structure whose weight is above 10000 tons.

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.
