What is the ASTM A131 standard?
The ASTM A131 specification is the Standard Specification for Structural Steel plates primarily used in ship construction. Steel grades covered in this specification require CVN Impact testing and are classified by minimum Yield Strengths.
What is a 131 material?
Steel plates ASTM A131 is a specification that covers structural steel plates, shapes, and bars intended primarily for shipbuilding. The steel plate specified under ASTM A131 is commonly used in the construction of offshore structures, including oil platforms and marine vessels.
ASTM A131 covers structural steel plates, shapes, and bars primarily for shipbuilding. It's often used in the construction of offshore structures like oil platforms and marine vessels. The standard specifies different grades, such as A, B, D, E, AH32, AH36, etc., differentiated by their mechanical properties, particularly yield strength and impact toughness.
What is the tensile strength of ASTM a131?
400 - 490 MPa 58000 - 71100 psi
| Physical Properties | Metric | English |

What is the equivalent of ASTM A131steel ?
ASTM A131 is a standard for shipbuilding steel, and equivalent grades can be found in various other standards, including those from other classification societies and national standards. Common equivalents include grades from DNV, GL, CCS, and JIS, as well as certain grades within the EN and Chinese standards.
ASTM A131 Grade AH36:
Equivalent grades include DNV NV A36, GL-A36, and CCS/A36.
ASTM A131 AH32:
Equivalent grades include DNV NV A32, GL-A32, and RINA RI/A32,
EN standard grades, like S355J2+N, can be comparable to ASTM A131 grades, especially AH36 and EH36
