ASTM A36 Steel Plate Stockists Ah32 Dh32 Eh32 Ah36 Dh36 Eh36 Carbon Steel Plate for Shipbuilding
Ah32 steel plate is used in shipbuilding and platform construction.The high tensile strength steel is shipbuilding steel plate grade AH32. Ah32 shipbuilding steel has good toughness, strength, corrosion resistance, processing qualities, and welding capabilities. ASTM A131 Ah32 steel plate can be utilized in the construction of ship hull structures weighing more than 10,000 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.
