High-strength marine-grade steel pipe manufactured to DNV AH36 shipbuilding grade. Engineered for long service life in demanding maritime and offshore applications, DNV AH36 pipes offer elevated yield and tensile strength combined with good ductility, making them suitable for hull construction, ship repairs and offshore platform piping.
Key features and typical uses:
- Marine and offshore applications: hulls, ship repairs, platform pipe joints, offshore oil-drilling platforms, container and bulk-cargo vessels, cruise ships and ferries
- Supplied forms: pipes (primary offering); also available in plates, sheets and bars for complementary shipbuilding and structural needs
- Approvals: commonly stocked and supplied to meet Det Norske Veritas (DNV) shipbuilding approval requirements; other classification approvals (e.g., ABS, RMRS) are often available on request
Mechanical properties (DNV AH36 grade — typical specified minima):
- Yield point (Re, min): 51 ksi (355 MPa)
- Tensile strength (Rm): 71–90 ksi (490–620 MPa)
- Elongation (min): 22% (2 in) and 19% (8 in)
Why select DNV AH36 pipe for your project:
- High tensile strength and reliable ductility for heavy-duty structural and hull applications
- Designed for welding and fabrication common in shipbuilding and offshore construction
- Readily integrated with other shipbuilding steels (plates, sheets, bars) for a consistent material specification across assemblies
If you require specific dimensions, wall thicknesses, testing certificates (mill test reports, material certificates) or classification society approvals for a procurement package, specify those requirements in your RFQ so suppliers can provide compliant quotes and lead times.
