Shipbuilding steel plate DH32 is manufactured to meet the standards of seafaring. DH32 plates are durable enough to withstand the rough and salty seas. DH32 steel has much higher tensile strength than marine grade D mild steel. Plate DH32 is much better suited to the efficient construction of large capacity ships.
DH32 steel plate has strength to withstand strong waves and currents. Along with being highly durable, DH32 shipbuilding steel is also very flexible, allowing shipbuilders to create different types of curves and angles to ensure the best performance for each vessel.
Shipbuilding steel plate DH32 is ideal for the offshore oil drilling platform, the hull and ship repairing. It is produced with the minimum tensile strength of 315MPa.
Shipbuilding steel plate DH32 plates chemical composition:
(heat analysis, % max unless otherwise specified)
| C | Si | Mn | P | S | Al Min. | Cb | V | Ti | Cu | Cr | Ni | Mo | Ca | N |
| 0.18 | 0.10-0.50 | 0.90-1.60 | 0.035 | 0.035 | 0.015 | 0.02-0.05 | 0.05-0.10 | 0.02 | 0.35 | 0.20 | 0.40 | 0.08 | 0.005 | - |
Notes: 1) The contents of any other element intentinally added is to be determined and reported.
2) If the content of soluble aluminum is not less than 0.015 %, the minimum required silicon content does not apply.
3) Columbium and niobium are considered interchangeable names for the same element and both names are acceptable for use in A01 standards.
4) The indicated amount of aluminum, columbium (niobium), and vanadium applies if any such element is used singly.
5) Ca element need not be reported on the mill sheet unless intentionally added.
