Different specifications of Shipbuilding Steel

The structural strength of the hull structural steel is divided according to its minimum yield point: general strength structural steel and high strength structural steel. The general strength structural steel of China Classification Society standard is divided into four quality grades: A, B, D, and E; the high-strength structural steel of China Classification Society standard is three strength grades and four quality grades:

AH32	AH36	AH40
DH32	DH36	DH40
EH32	EH36	EH40
FH32	FH36	FH40
