NK D

NK D Shipbuilding steel plate
Shipbuilding steel NK D is a common tensile strength steel . NK D steel plate is usual for shipbuilding and oil platform purpose. NK 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 NK 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.

Note: In the list , Rm: .tensile strength,Re: Yield strength,A%: elongation, E.T: experimental temperature,L: lengthways, C: crosswise.
NK D steel plate Condition Of Delivery

Grade	category	The thickness of steel
		≤ 12	>12.5-25	>25-35	>35-50	>50-100
NK D	Plate/sheet	A(50)			N(50) CR(50) TM(50)	N(50) TM(50) CR(25)
	Profile steel				N(50) CR(50) TM(50) AR*(25)	-

Note: 1. delivery condition: A =Any ; N=Normalized ; CR=Control Rolled ; TM=TMPC, Temperature - deformation control rolling; AR*= Can be hot rolled with the agreement of Classification Society ; CR*=Can be control rolled with the agreement of Classification Society .
2. The Figure in the ( ) means the sampling volume to do the impact test, the unit is Ton.(-) means without impact test.
