LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS AH32 Shipbuilding steel plate

Capable Classification Society Quality Authentication from LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS,Ah32 steel plate is used for shipbuiling&platform.The shipbuilding steel plate grade AH32 is the high tensile strength steel. Ah32 shipbuilding steel  has good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties. ASTM A131 Ah32 steel plate  can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.

AH32 Shipbuilding steel plate specification:
Thickness: 4mm to 260mm, 
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

Ah32 steel plate Chemical Composition %

Grade	C max	Si  max	Mn	P max	S  max	Als  min	Ti max	Cu max	Cr max	Ni max	Mo max
AH32	0.18	0.50	0.90-1.60	0.035	0.035	0.015	0.02	0.35	0.20	0.40	0.08

Note: Generally speaking CE will be ≤ 0.40%. If the delivery condition is TMPC, the CE will be : ≤ 0.36% (thickness ≤ 50mm),≤0.38%( when the thickness >50-100). Ceq% =(C+Mn)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
