Shipbuilding steel Grade D is a common tensile strength steel . ASTM A 131 Grade D steel plate is usual for shipbuilding and oil platform purpose.D shipbuilding steel is the Hull structural steel which with a good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.The shipbuilding steel grade D is mainly used in the manufacture of the ship's hull structure whose weight is below 10000 tons,and usually do navigation around coastal and river area.
Grade D Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
Grade D steel plate Chemical Composition
Note: CE: C+1/6Mn ≤ 0.40% Cu ≤ 0.35%,Ni ≤ 0.30%≤
Grade D steel plate Mechanical Property
Note: In the list , Rm: .tensile strength,Re: Yield strength,A%: elongation, E.T: experimental temperature,L: lengthways, C: crosswise.
