ASTM A514 Steel Plate

ASTM A514 Steel Plate

ASTM A514 steel plate is a quenched and tempered alloy steel used in applications that require a particularly high yield strength.  A514 has a minimum yield strength of 100 ksi (690 MPa). Grades B, S and E are by far the most common, however we have other grades available.  Each grade is limited to a range of thicknesses.  All grades have the similar mechanical properties, but vary in chemical makeup and thickness. PGI can cut A514 steel with a variety of methods.  And we can machine using conventional equipment and carbide tools.  ASTM A514 steel has excellent weldability.

A514 steel plate is commonly used in heavy equipment parts that require a higher strength at a reduced weight, such as crane booms, mining equipment, hauling equipment, and lifting equipment. In addition, A514 steel is particularly well suited for wear resistant steel plates used for large tooling, digging, clearing, and scraping.  Examples include scraper bars for coal mining conveyors and conveyor flights.  Also, rock scraper blades and bucket scrapers for large mining and farm implements often use A514.  Other applications for A514 may include wear plates, screen plates, and wear bars.  And finally, large mining equipment and construction equipment often have heavy wear demands provided by A514.
