CCS FH40 steel plate for high-strength ships and offshore platforms

CCS FH40 steel plate executive standard: GB/T712
Delivery status of CCS FH40 steel plate: delivery in normalized, TMCP (temperature deformation controlled rolling), QT (quenching+tempering) heat treatment status. The demander can select the heat treatment status according to actual needs, and can attach flaw detection standard requirements, flaw detection grade requirements, alloy element composition control requirements, thickness direction performance requirements, etc., or attach classification society certification, such as ABS/FH40, etc.

CCS FH40 steel plate is a structural steel plate for high-strength ships and offshore platforms. The impact temperature of CCS FH40 steel plate is - 60℃, and it has good low-temperature impact performance. Because of the complexity of the navigation environment of large ships, it is necessary to require ship steel to have good toughness. Especially in cold environments, it is necessary to have excellent low-temperature aging impact toughness, which requires a low ductile brittle transition temperature, which is also the technical key of Class F high-strength ship plates.
