ASTM A131 Grade EH36 is a high-strength, low-alloy structural steel plate primarily used in the construction of ships and marine structures. It is specified under the American Society for Testing and Materials (ASTM) standard A131/A131M.
The properties of ASTM A131 Grade EH36 steel include:
Tensile Strength: The minimum tensile strength of ASTM A131 Grade EH36 steel is 490-620 megapascals (MPa) or 71,000-90,000 pounds per square inch (psi).
Yield Strength: The minimum yield strength of ASTM A131 Grade EH36 steel is 355 MPa or 51,000 psi.
Elongation: The typical elongation at break for ASTM A131 Grade EH36 steel is around 21%.
Charpy V-Notch Impact Test: ASTM A131 Grade EH36 steel is required to undergo Charpy V-notch impact testing at -40 degrees Celsius (-40 degrees Fahrenheit) with a minimum average energy absorption value of 34 joules.
Corrosion Resistance: ASTM A131 Grade EH36 steel offers good resistance to corrosion, making it suitable for marine environments.
These properties make ASTM A131 Grade EH36 steel well-suited for shipbuilding and offshore applications where high strength, excellent weldability, and good toughness are critical requirements. It is commonly used in the construction of hulls, decks, and other structural components in various types of vessels, such as tankers, bulk carriers, and offshore platforms.
