AH36 Steel Plate for Shipbuilding - Price per Ton, ASTM A131 Certified

Price for AH36 steel plate for shipbuilding represents a critical consideration for marine construction projects requiring certified structural materials. This high-strength hull structural steel finds extensive application in commercial vessel construction, offshore platforms, and maritime infrastructure where superior mechanical properties and seawater corrosion resistance are paramount. Manufactured to ASTM A131/A131M standards, AH36 grade steel delivers exceptional weldability combined with robust tensile strength of 490-620 MPa, making it the preferred choice for shipyards and marine fabricators seeking cost-effective solutions without compromising structural integrity.

What is Price for AH36 Steel Plate for Shipbuilding?

AH36 steel plate is a normalized high-strength low-alloy structural steel specifically engineered for shipbuilding applications per ASTM A131 Grade AH36 specifications. The designation "AH" indicates higher strength characteristics compared to ordinary strength grades, with "36" representing the minimum yield strength of 355 MPa (51.5 ksi). This marine-grade material undergoes controlled rolling and normalizing heat treatment to achieve optimal grain structure, ensuring consistent mechanical properties throughout thickness ranges from 6mm to 150mm.

Price for AH36 Steel Plate for Shipbuilding Technical Specifications

Chemical composition limits per ASTM A131/A131M include carbon content of 0.18% maximum, manganese 0.90-1.60%, silicon 0.50% maximum, phosphorus 0.035% maximum, and sulfur 0.035% maximum. The material exhibits tensile strength ranging from 490 MPa to 620 MPa with minimum yield strength of 355 MPa at room temperature. Charpy V-notch impact testing demonstrates energy absorption of 27 Joules minimum at -20°C, confirming excellent low-temperature toughness essential for maritime environments. Density measures 7.85 g/cm³ at 20°C with thermal conductivity of 50 W/m·K.
