Product Description

AH36 Shipbuilding steel plate

Specification

Ah36 steel plate is used for shipbuiling&platform.The shipbuilding steel plate grade AH36 is the high tensile strength steel. Ah36 shipbuilding steel has good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties. ASTM A131 Ah36 steel plate can be used in the manufacture of the ship's hull structure whose weight is more than 10000 tons.

AH36Shipbuilding steel plate specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.

Chemical Composition % of Ah36 shipbuilding steel plate

Grade	C max	Si max	Mn	P max	S max	Als min	Ti max	Cu max	Cr max	Ni max	Mo max
AH36	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.
