A131 Grade EH36 steel plate,A131 Grade AH36 steel plate,A131 Grade A steel plate

High-strength shipbuilding steel plates produced to the ASTM A131 specification, offered in Grades A, AH36 and EH36. These flat plates are intended for hull structure, decks, bulkheads and general vessel construction and repair. EH36 is the higher-strength, low-temperature toughness grade commonly used where greater yield strength and improved fracture resistance in cold environments are required.

Key features

• Conforms to ASTM A131 shipbuilding plate grades A, AH36 and EH36
• EH36: high-strength, improved low-temperature toughness for cold-service applications
• Good weldability and formability for typical shipbuilding fabrication and repair processes
• Supplied in flat plate form suitable for cutting, forming and welding

Typical applications

• Newbuild and repair of commercial and military vessels
• Offshore platforms and marine structures
• Structural components requiring high yield strength and impact resistance in low temperatures

Procurement notes for buyers

• Specify required grade (A, AH36 or EH36), plate thickness, dimensions and surface finish at inquiry
• Request mill test certificates (chemical analysis and mechanical test reports) to verify compliance with ASTM A131
• Confirm any additional processing (cut-to-size, beveling, drilling, heat treatment) and packing/shipping requirements prior to order

If you require assistance matching grade, thickness and supply condition to a specific marine or offshore application, provide intended service conditions (temperature, loading) and fabrication requirements so the supplier can recommend the correct grade and furnish appropriate test documentation.
