NK AH36 DH36 EH36 FH36 shipbuilding steel plates

NK AH36, DH36, EH36, and FH36 are high-tensile strength marine steel grades approved by Nippon Kaiji Kyokai (ClassNK). They feature excellent toughness and corrosion resistance, suitable for harsh marine environments. These plates are primarily used for building large vessels, offshore platforms, and critical structural components requiring high strength and low-temperature impact resistance.
