Grade D Shipbuilding Steel Plate

- Sep 11, 2017 -

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.
