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.
