CCS B Shipbuilding Steel

CCS Grade B, CCS B grade steel is an ordinary strength structural steel for ships, hull structures and ocean engineering projects. CCS B, CCS Grade B shipbuilding steel products are available in various sizes and shapes like plates, sheets, bars, angles, profiles, and bulb flats.

Hull structural steel can be divided into ordinary strength steel, higher strength steel and extra high tensile strength steel. The ordinary strength hull structural steel of China Classification Society has four quality grades: Grades A, B, D and E (ie CCS A, CCS B, CCS C, CCS D). The higher strength structural steel of China Classification Society standard is three Strength levels (32 grades, 36 grades, 40 grades), four quality classes (Grades AH, DH, EH, FH).

CCS Extra-high strength shipbuilding steel grades:

CCS AH420	CCS DH420	CCS EH420	CCS FH420
CCS AH460	CCS DH460	CCS EH460	CCS FH460
CCS AH500	CCS DH500	CCS EH500	CCS FH500
