Products FAQ

What is the main difference between CCS Grade A steel and CCS Grade D steel?

The main difference between the two lies in the temperature requirements for impact testing.

CCS Grade A: No impact testing is required for standard thicknesses (≤50 mm); impact testing in accordance with the specifications is only required when the thickness exceeds 50 mm.

CCS Grade D: A Charpy V-notch impact test must be conducted at 0°C to ensure safe use in colder marine environments.
