Accreditation Administration System:
KR Grade AH32,KR Grade DH32,KR Grade EH32 and KR Grade FH32 shipbuilding steel plate under KR rule.
all the grades owned minimum 315Mpa yield strength and different impacting test temperatures.For KR Grade
FH32,it shall be less Carbon contains as maximum 0.16%,and N is 0.009%.For giving you a clear knowledge
of these grades,now we list the following comparasion table:
