DH460 structural steel for ships and marine engineering

DH460 structural steel plate is a steel plate with a thickness of not more than 150mm used in the manufacture of ocean-going, coastal and inland navigation ships, fishing boats and marine engineering structures. For DH460 steel plates with Z-direction requirements, add Z25 and Z35 to the suffix. DH460 steel is used for ultra-high-strength ships and marine engineering structures.

The size, shape, weight and allowable deviation of ship plate DH460 shall comply with the regulations of GDH460/T709, and the deviation under thickness is -0.3mm.

DH460 structural steel plate delivery status:
DH460 steel plate is usually delivered in quenched and tempered, normalized, thermomechanical rolled + tempered state.

DH460 ship plate chemical composition:
C≤0.21, Si≤0.55, Mn≤1.7, P≤0.025, S≤0.025, N≤0.02
The added alloying elements and grain refinement elements Al, Nb, V, Ti shall comply with the relevant standards approved by the classification society. The crack susceptibility coefficient Pcm should be calculated by the formula instead of carbon equivalent, and its value should meet the standards approved by the classification society.

DH460 steel specifications of classification societies:
ABS, BV, CCS, DNV, GL, KR, LR, NK, RINA classification societies can produce, certified ABS-DH460, BV-DH460, CCS-DH460, DNV-DH460, GL-DH460, KR-DH460, LR -DH460, NK-DH460, RINA-DH460
