In KR classification society, common strength structural shipbuilding steel grades contains KR Grade A,KR Grade B,KR Grade D and KR Grade E steel plates. High strength structural shipbuilding steel grades are KR Grade AH32, Grade AH36, GRADE AH40, Grade DH36,Grade DH40,GRADE FH32, KR GRADE FH36 and Grade FH40. Now we analysis the common grades property as belows:
