High toughness marine grade FH40 ship structure steel plate owns higher values in yield strength and tensile strength than common strength ship steel plate. And it can be used in high mechnical structruals and cranes in ships and vessels. FH40 ship structure steel plate shall be normalized, thermomechanical control processed, or quenched and tempered. FH40 ship structure steel plate is supplied with EN10204 3.2 MTC stamped by ABS, LR, BV, DNV GL, RINA, NK, CCS, KR, RMRS or other classification societies as your requirements.
High toughness marine grade FH40 ship structure steel plate chemical composition:
(heat analysis, % max unless otherwise specified)
Notes: 1) If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
2) N content is 0.012 if aluminum is present.
High toughness marine grade FH40 ship structure steel plate mechanical property:
||Charpy V Impact Test
FH40 ship structure steel equivalent grades:
High toughness marine grade FH40 ship structure steel plate can achieve the impact toughness at Celsius degree -60°. FH40 ship structure steel plate is mainly used in the ship project and ocean offshore structural project, for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components.
