Main Applications of CCS Grade AH36 Shipbuilding Steel Plates in the Shipbuilding and Offshore Engineering Industries
CCS Grade AH36 shipbuilding plate is a high-strength steel certified by the China Classification Society (CCS) for use in shipbuilding and offshore engineering. It is widely used in hull construction, offshore oil and gas platforms, offshore support facilities and port engineering. Thanks to its excellent strength, toughness and suitability for marine environments, CCS Grade AH36 shipbuilding plate has become one of the key steels used in large and medium-sized offshore engineering projects.

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.
Corrosion Resistance of CCS Grade A Shipbuilding Steel Plates in Marine Environments and Coating Solutions
CCS Grade A is a normal-strength structural steel plate for ship hulls. It possesses only moderate resistance to seawater corrosion, with a corrosion rate significantly higher than that of weathering steel and high-strength marine steel plates. Consequently, in marine environments, this steel grade must rely on a combined protective system comprising coatings and cathodic protection to ensure long-term, reliable service. This paper analyses the corrosion resistance of CCS Grade A shipbuilding steel plates in marine environments and systematically reviews the corresponding coating protection solutions.

Differences between and Selection of CCS Grade A, B, D and E Ordinary-Strength Marine Steel Plates
Normal-strength CCS shipbuilding steel plates are classified into four grades: A, B, D and E. All have a yield strength of ≥235 MPa; the sole key distinction lies in the impact test temperature, which directly determines their suitability for specific maritime regions, procurement prices and construction environments. Below is a summary of the main differences between these grades, along with recommendations for procurement and selection.
