Our range of Shipbuilding Plates are manufactured in accordance to the guidelines of ASTM A131 standards. The A131 covers various grades like ordinary strength A, B, CS & E and higher strength AH, DH, EH & FH. We also provide these plates in AH36, DH36 and EH36 grades that are chemically similar but tested on different temperatures for the Charpy V–Notch test. Furthermore, our range is used for manufacturing containers, bulk cargo vessels, cruise ships, ferries and yachts.
The standard composition is as below for AH36, DH36 and EH36:
AH36:
Thickness: 5-150mm
Width: 1500, 2000, 20555 and 3000 mm
Length: up to 12000 mm
DH36:
Thickness: 5-150 mm
Width: 1500, 2000, 20555 and 3000 mm
Length: up to 12000 mm
EH36:
Thickness: 5-150mm
Width: 1500, 2000, 20555 and 3000 mm
Length: up to 12000 mm
