The steel for shipbuilding and oil platform---EH40, 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.
EH40 shipbuilding steel plate specification:
Thickness: 4mm to 260mm, Width: 1200mm to 4000mm, Length: 3000mm to
18000mm.
EH40 shipbuilding steel Mechanical Property Chemical Composition %

| EH40 | 0.18 | 0.50 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02 | 0.35 | 0.20 | 0.40 | 0.08 | 0.02-0.05 | 0.05-0.10 |
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.
