Due to the complexity of the navigation environment of large ships, CCS FH40 steel plate must have good toughness. Especially in cold environment, CCS FH40 steel plate must have excellent low temperature aging impact toughness. CCS FH40 steel plate adopts low-carbon microalloy mode and TMCP production process to achieve the comprehensive matching of strength and low-temperature toughness.
