Shipbuilding Steel Plate Standards from Different Countries

Shipbuilding steel plates are produced under the approval of production methods of classification societies in different countries refers to offshore and marine steels.

  • ABS (American Bureau of Shipping)
  • BV (Bureau Veritas)
  • CCS (China Classification Society)
  • DNV (Det Norske Veritas)
  • GL (Germanischer Lloyd)
  • HR (Hellenic Register of Shipping)
  • KR (Korean Register of Shipping)
  • LR (Lloyd’s Register of Shipping)
  • NK (Nippon Kaiji Kyokai)
  • RINA (Registro Italiano Navale)
  • RS (India Register of Shipping)

Shipbuilding Steel Plate Grades: A, B, D, E, AH32/36/40, DH32/36/40, EH32/36/40

  • According to its yield strength, shipbuilding plate of can be divided into below grades:
  • Grade A steel is the impact force subjected to normal temperature (20 ° C).
  • Grade B steel impact force at 0 °C.
  • Grade D steel impact force at -20 °C.
  • Grade E steel impact force at -40 °C.
  • High-strength shipbuilding steel plate can be further divided into: AH32, DH32, EH32; AH36, DH36, EH36 and AH40, DH40, EH40.
  • The general grades A, B, D, and E are distinguished according to the impact temperature of the steel. The impact values of all grades of steel are the same.
  • High-intensity hull structure steel preheating requirements: For all AH, DH, EH plate thickness greater than 30mm angle, butt joints, shall be preheating to 120 ~ 150 °C before welding.
  • For thickness of the plate ≤ 30mm, the ambient temperature is below 5 ° C, preheated to 75 ° C; Ambient temperature below 0 ° C, preheated to 75 ~ 100 ° C.
