LR AH40 Shipbuilding Steel

LR AH40 Ship plate is Refer to the hot-rolled steel sheet that used to manufacture the hull structure and it is produced by the classification society's construction specifications. LR AH40 steel is mainly used to manufacture hulls, decks, for ocean, coastal and inland navigation shipping vessels etc.

LR AH40 ship steel Classification

The steel for hull structure is divided into two types: general strength and high strength steel. The quality of general strength steel is divided into four grades: A, B, D, and E. High-strength steel is divided into two strength grades and three quality grades: AH32. , DH32, EH32, AH36, DH36, EH36.

LR AH40 classification society certification:

AH40 Shipbuilding Steel has been certified by nine classification societies such as American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, and Korean KR.

Shipbuilding steel grade, AH32, AH36, DH32, DH36, EH32, EH36, EH40, FH32, EH36 are the high tensile strength steel. If you need AH32, AH36, DH32, DH36, EH32, EH36, EH40, FH32, EH36 shipbuilding steel plates/sheet/bar or chemical composition, mechanical property, and yield strength, please contact us, we will try our best to help you.
