Accreditation Administration System:
The best common acceptance by shipyards,ABS rules contains such gardes as ABS Grade AH36,
ABS Grade EH36,ABS GRADE FH36,ABS Grade DH36.All these grades owned 355Mpa yield
strength and minimum 490Mpa tensile strength.Steel mark on the delivery steel plates shall be AB/AH36,
AB/DH36,AB/EH36 and AB/FH36. Now we give you the comparasion table of these common grade as
belows:
