ASTM A131 FH36, F means quality grade of the high strength hull structural steel. Hull structure steel includes general strength structural steel and high strength structural steel. General strength hull structural steel is divided into A, B, D, E and high strength hull structural steel is combined by four quality levels(A, D, E, F)and three strength levels(32、36、40). So high strength hull structural steel includes A32、D32、E32、F32, A36、D36、E36、F36, A40、D40、E40、F40.

C max | Si max | Mn | P max | S max | Als min | Ti max | Cu max | Cr max | Ni max | Mo max | Nb | V | N max | |
FH36 | 0.16 | 0.50 | 0.90-1.60 | 0.025 | 0.025 | 0.015 | 0.02 | 0.35 | 0.20 | 0.80 | 0.08 | 0.02-0.05 | 0.05-0.10 | 0.009 |
Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.38% (thickness ≤ 50mm),≤0.40%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.

ASTM A131 FH36 steel plate, FH36 steel is a kind of steel for shipbuilding and platform. Shipbuilding steel plate FH36 is the high tensile strength steel. As a professional shipbuilding steel plate exporter, Katalor Enterprises can supply steel plate FH36. ASTM A131 FH36 shipbuilding steel plates can be used in the manufacture of the ship's hull structure whose weight is below 10000 tons.
