ASTM A131 FH36 steel

ASTM A131 FH36 steel

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.

FH36 shipbuilding steel plate Chemical Composition %

  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.
