All BV steels are standard carbon steels. As with other grades of steel, they have a specific gravity of 7.8.Higher-strength BV shipbuilding steel comes in six grades of two strengths, The BV DH 32 grade steel plates have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-570 MPa).
BV DH32 Steel Grade Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
