ASTM
A131 Grade DH32 steel is a kind of hot rolled high tensile strength
shipbuilding steel. Higher Strength—Grades AH, DH, EH, and FH with a specified minimum yield point of 46 ksi [315 MPa], 51 ksi [350 MPa], or 57 ksi [390 MPa]. The 32 grades have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa).
ASTM A131 DH32 Shipbuilding Steel Application
ASTM A131 Grade DH32 steel plates are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment. A131 DH32 shipbuilding steel plates also can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components.
ASTM A131 DH32 Steel Plates Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
