Heat Treatment Techniques for CCS EH32 Shipbuilding Steel Plates

Heat treatment is a key process that determines the mechanical properties, flatness and service life of CCS EH32 shipbuilding steel plates. Improper processing can lead to insufficient low-temperature toughness, uneven hardness and reduced weldability, thereby failing to pass the certification inspection by the China Classification Society (CCS). Currently, two main heat treatment processes are used for CCS EH32 shipbuilding steel plates: normalising and TMCP (Thermomechanical Control Processing).
