Shipbuilding Steel Plate - AH36|DH36|EH36|FH36

ABS High Strength Steel Plates AH DH EH FH

High Strength Steel Plate for Shipbuilding

As, morden ships sizes are much larger than old days, a series of high strength steel plate are developed for shipbuilding, according to ABS Classification Society, 4 basic steel grades are as follows: AH36, DH36, EH36, FH36. AGICO is able to supply all steel grades with comprohensive sizes, and delivery state can be specified by customer.

What Makes High Strength Steel Plate

As Shipbuilding steel plate are used in corrosive sea environment, steel plate with high strength and corrosion resistance is more suitable for building ships. Additionally welding performence is also a key requirement for shipbuilding steelplate. But how to make shipbuilding plate with higher strength? Take F serie for example, carbon element is being controlled in hot rolling process, and TMCP technology is the key for manufacturing high quality shipbuilding plate.
