Welding Process for CCS Grade AH32 Shipbuilding Steel Plates
CCS AH32 is a high-strength, low-alloy structural steel for shipbuilding and offshore engineering, with a yield strength of ≥315 MPa and a carbon equivalent of ≤0.40%, offering good weldability. Key welding points: low-hydrogen welding consumables, appropriate preheating and interpass temperature control, multi-pass welding, strict control of heat input, and post-weld inspection to prevent cold cracks and embrittlement.

The differences between the CCS AH32, DH32 and EH32
CCS AH32, DH32 and EH32 are all high-strength marine structural steels with a yield strength of ≥315 MPa; the key differences between them lie in their alloy composition, low-temperature impact toughness and delivery condition.
