ASTM A131 EH32 steel

ASTM A131 EH32 steel

EH32 steel is high strength hull structural steel under the standard ASTM A131. Katalor Industry is a professional EH32 steel supplier.

1,General hull structural steel A, B, D, E is identified according to the steel shock temperature, impact value of each grade of steel are the same, not divided according to the strength grade.

A grade steel refers to at room temperature (20 ℃) impact.

Grade B steel is in 0 ℃ impact.

D steel is the impact under - 20 ℃.

E steel is under - 40 ℃ impact.

High strength hull structural steel is divided into AH32 DH32 EH32 AH36 DH36 EH36.

2,High strength hull structural steel preheating requirements:For AH, DH, EH, thickness is more than 30 mm angle and seam, preheat to 120 ~ 150 ℃ before welding.

3,The steel plate thickness≤30mm and the environment temperature<5℃, preheat to 75~100℃.

4,For TMCP steel, it can not preheat before welding.

EH32 shipbuilding 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
EH32 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.
