CCS DH32 steel plate is mainly used to build vessels which are sailing in low temperature oceans. CCS DH32 steel plate owns the minimum yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa).

CCS DH32 steel plate chemical composition:

Grade	C %	Si %	Mn %	P %	S %	V %	AL %	Cr %
CCS DH32	0.18	0.10-0.50	0.90-1.60	0.035	0.035	0.05-0.10	0.015	0.20
	Cu %	Mo %	Nb %	Ni %	Ti %
	0.35	0.08	0.02-0.05	0.40	0.02

CCS DH32 steel plate mechanical properties:

Grade	Rm (MPa)	Re(MPa) min	A% min	Akv/J min
