Introduction

High strength shipbuilding steel grades include AH, DH, EH, and FH with a specified minimum yield point of 46 ksi [315MPa], 51 ksi [350MPa], or 57 ksi [390MPa].

Grades AH32, DH32, EH32 and FH32's yield strength is not less than 315MPa, and the tensile strength is 440~570Mpa. Grades AH36, DH36, EH36 and FH36's yield strength is not less than 355MPa, and the tensile strength is 490~620MPa. Meanwhile, the yield strength of AH40, DH40, EH40 and FH40 is not less than 390MPa, and the tensile strength is 510~660MPa.
