The steel for shipbuilding and oil platform---FH32 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.
FH32 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 |
N max |
| FH32 | 0.16 | 0.50 | 0.90-1.60 | 0.025 | 0.025 | 0.015 | 0.02 | 0.35 | 0.20 | 0.80 | 0.08 | 0.009 |
Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100).
Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
