Characteristics and Applications of ASTM A131 AH36 Steel
Characteristics
High Strength: AH36 steel plate possesses high yield strength and tensile strength. The yield strength is not less than 355 MPa, and the tensile strength ranges from 490 to 620 MPa. This enables it to withstand significant loads and impacts, meeting the strength and stability requirements for ship structures.
Good Toughness: AH36 steel plate maintains good toughness even at low temperatures, ensuring the integrity and stability of the structure in the event of accidents such as collisions or groundings, effectively preventing brittle fracture.
Excellent Weldability: AH36 steel plate exhibits good machinability and weldability, maintaining stable performance during processing and welding. It has undergone welding procedure qualification and meets the requirements of relevant specifications.
Corrosion Resistance: AH36 steel plate typically requires surface treatment (such as sandblasting, rust removal, and painting) to enhance its resistance to seawater corrosion and extend the service life of the hull structure.
Machinability: AH36 steel plate can be subjected to processes such as cutting, bending, and stamping to meet the needs of different shapes and sizes. It demonstrates good plasticity and formability during both cold and hot working processes, adapting to complex technological requirements.
Applications
Shipbuilding: This includes the manufacture of key components such as the main structure, deck, and cabins of ships, as well as high-strength parts like ship cranes and ship devices.
Offshore Engineering: Such as offshore platforms, cross-sea bridge structures, and offshore derricks. Its corrosion resistance and good mechanical properties ensure the safe and stable operation of offshore engineering facilities, providing reliable support for the development and utilization of marine resources.
Bridge Construction: It can withstand heavy loads and complex stresses in large-span bridges, ensuring their safety and stability.
Construction Field: It can be used in the construction of high-rise buildings, large public facilities, and other structures, enhancing their seismic resistance and load-bearing capacity.
