Welding of CCS Grade A Shipbuilding Steel Plates
CCS Grade A is a general-purpose structural steel for ship hulls certified by the China Classification Society (CCS). It has a yield strength of ≥235 MPa and a tensile strength of 400 - 520 MPa. It has no low-temperature impact requirements, a low carbon equivalent and good weldability, making it suitable for inland waterway and coastal vessels, as well as non-critical structures. Key points for welding CCS Grade A shipbuilding steel plates: No preheating required for thin plates, appropriate welding consumables, low-hydrogen welding consumables for critical joints, and CCS process approval.

CCS A Marine Structural Steel Equivalent Grade
In global shipbuilding projects, it is essential to understand the equivalence between the regulations of different classification societies. Grade A marine structural steel has direct equivalents in the standards of all major classification societies, thereby facilitating multi-class certification and cross-border procurement.
