GRADE B Steel plates to ASTM A131 for shipbuilding are available from Katalor Industry. A131 covers a number of different grades – some are ordinary strength A, B, D and E, whilst others are higher strength – AH, DH, EH and FH. Katalor Industry supplies AH36, DH36 and EH36 which are chemically similar but which are tested as different temperatures for the Charpy V–Notch test.
Our steel plates are suitable for container and bulk cargo vessels as well as cruise ships, ferries and yachts.
