The steel for shipbuilding and oil platform---EH40 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.
EH40 steel Chemical Composition
Grade | C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr max |
Ni max |
Mo max |
Nb | V |
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.
