CCS FH40 Marine Steel Plate
FH40 structural steel for ship hull can be divided into general strength structural steel and high-strength structural steel plate according to its yield strength, China Classification Society specification standards for general strength structural steel is divided into: A, B, D, E four quality levels.
FH40 hull structural steel plate for offshore platforms requires good low-temperature impact performance, good toughness and low toughness and brittle transition temperature.CCS/FH40 steel plate impact temperature of -60 ℃, especially in the cold environment need to have excellent low-temperature aging impact toughness.

FH40 shipbuilding plates product details
CCS/FH40 high strength shipboard executive standard: GB/T712-2011.
CCS/FH40 high-strength ship plate delivery state: normalized, TMCP (temperature - deformation control rolling), QT (quenching + tempering) heat treatment state delivery, the demand side according to the actual needs of the choice of heat treatment state, can be attached to the requirements of the flaw detection standards, flaw grade requirements, alloying elements, composition control requirements, the thickness of the direction of the performance requirements, and so on, can be attached to the classification society certification, such as the ABS / FH40 etc.
