ASTM A514 Grade B is a high-strength, quenched and tempered Alloy steel plate primarily used in structural applications. The properties of A514 Grade B material include:
Tensile Strength: The minimum tensile strength of A514 Grade B is 690-895 megapascals (MPa) or 100-130 thousand pounds per square inch (ksi).
Yield Strength: The minimum yield strength of A514 Grade B is 620 MPa or 90 ksi.
Elongation: The typical elongation at break for A514 Grade B is around 18%.
Impact Toughness: A514 Grade B exhibits good impact toughness at low temperatures, making it suitable for cryogenic applications.
Weldability: A514 Grade B has excellent weldability and can be welded using standard methods and practices. Preheating and interpass temperature control may be necessary to minimize the risk of cold cracking.
Formability: A514 Grade B has relatively good formability, allowing it to be bent and formed into various shapes. However, it has a high yield strength, so greater force may be required during forming processes.
The combination of high strength, good weldability, and favorable mechanical properties makes A514 Grade B suitable for applications in industries such as construction, mining, transportation, and heavy equipment manufacturing.
