Products Description
ASTM A514 steel is an alloy steel formulated for primary forming into wrought products. It can have a very high tensile strength among the wrought alloy steels in the same category in the database.
The properties of ASTM A514 steel include eight common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below.
The graph bars on the material properties cards further below compare ASTM A514 steel to: wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Products Application
A514 steel plate is typically used for applications that require high wear resistance and superior strength without sacrificing weldability and machinability. It is widely employed in construction equipment, such as cranes, excavators, and loaders, as well as in industrial manufacturing, including heavy-load machines and structural components subjected to high stress.
A514 steel plate offers a minimum yield strength of 690 MPa (100 ksi) and a tensile strength of 760–940 MPa (110–136 ksi), with elongation typically around 12–15% depending on plate thickness. Its Brinell hardness ranges from 200–260 HB, providing excellent wear resistance under heavy-duty conditions.
The steel is typically available in thicknesses from 6 mm to 150 mm, with widths of 1,500–3,000 mm and lengths up to 12,000 mm, making it suitable for large structural components. Its combination of high strength, machinability, and weldability allows engineers to fabricate durable, cost-effective, and reliable components for demanding applications.
