Difference between CCS EH32 and CCS EH36 steel plate

CCS EH32 is a high-strength shipbuilding steel plate certified by the China Classification Society (CCS) . The "E" grade signifies it is impact tested at -40°C . It has a minimum yield strength of 315 MPa and tensile strength ranging from 440 to 590 MPa . Minimum elongation is 22% . The chemical composition is strictly controlled with carbon ≤0.18% and manganese 0.90-1.60% . It is widely used for hull construction, offshore platforms, and marine components.

CCS EH36 is also a high-strength marine steel plate certified by CCS with impact toughness tested at -40°C . The "36" denotes a minimum yield strength of 355 MPa and tensile strength ranging from 490 to 620 MPa . Minimum elongation is 21% . The chemical composition features similar limits with carbon ≤0.18% and manganese 0.90-1.60%, plus microalloying elements for enhanced properties . This grade is designed for more demanding structural components in shipbuilding and offshore platforms.

Both CCS EH32 and CCS EH36 are CCS-certified high-strength marine steels with excellent low-temperature toughness tested at -40°C, ensuring reliable performance in harsh marine environments . Their primary difference lies in strength level: EH32 offers a minimum yield strength of 315 MPa with tensile strength of 440-590 MPa, suitable for general high-strength hull construction, while EH36 provides a higher minimum yield strength of 355 MPa with tensile strength reaching 490-620 MPa, designed for more demanding load-bearing applications requiring superior strength. Both grades feature controlled chemical composition and maintain good weldability for critical marine service.
