Introduction

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.

A131/D general Strength Chemical Composition:

Grade	The Element Max (%)
Grade	C	Si	Mn	P	S	C+Mn/6
A131/D	0.21	0.10-0.35	0.60	0.035	0.035	0.40

Crack Sensitivity: Pcm = (C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B)%
Carbon Equivalent: Ceq = 【C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15】%
