DNV AH36 Plate Shipbuilding Steel

DNV AH36 shipbuilding steel is a high-strength marine-grade steel supplied in plates, sheets and bars for new build and repair projects. Engineered for long service life in demanding marine and offshore environments, DNV AH36 combines elevated yield and tensile strength with good formability for hulls, decks and structural members.

Key features

• Grade: DNV AH36 (high tensile shipbuilding steel)
• Supply forms: plates, sheets, bars; cut-to-size and fabrication-ready supply available on request
• Typical mechanical properties: yield strength ≈ 51 ksi (355 MPa); tensile strength ≈ 71–90 ksi (490–620 MPa)
• Certification: commonly supplied with DNV approval; stocks and batches may also carry approvals or classification documentation from other societies (for example ABS or RMRS) depending on the lot and customer requirements

Typical applications

• Ship hulls, decks and topside structures
• Ship repair and retrofit work
• Offshore structures including drilling platforms and platform pipe joints
• Cargo and container vessels, bulk carriers, ferries and cruise ships

Quality and supply options

• Supplied to industry-standard shipbuilding plate dimensions; custom sizes and processing (profiling, shearing, edge preparation) can be arranged to project specifications
• Available with mill test certificates and classification society documentation when required
• Suitable for welding and conventional shipbuilding fabrication processes; final fabrication and testing scope can be specified in RFQ

Ordering

For project quotations, indicate required form (plate/sheet/bar), dimensions and thickness, quantity, required certificates or classification approvals, and any cut-to-size or processing instructions. Lead times and packing for export will be provided per inquiry.
