Accreditation Administration System:
Under ABS rolling rule,according to the different impacting test temperature,ABS Grade AH32,
ABS Grade DH32,ABS Grade EH32 and ABS Grade FH32 shall be with minimum yield strength 315 Mpa.
The delivery condition shall be AR,CR,Normalized or TMCP.The relative grades are ABS Grade
AH36,ABS Grade DH36, ABS Grade EH36, ABS Grade FH36, ABS Grade AH40, ABS Grade DH40, ABS Grade
EH40, ABS Grade FH40.Now we list the difference between these grade as belows,please check it:
