A514 is a particular type of high strength steel, which is quenched and tempered alloy steel, with a yield strength of 100,000 psi (100 ksi or approximately 700 MPa). The ArcelorMittal trademarked name is T-1.^[1] A514 is primarily used as a structural steel for building construction. A517 is a closely related alloy that is used for the production of high-strength pressure vessels.

This is a standard set by the standards organization ASTM International, a voluntary standards development organizations that sets technical standards for materials, products, systems, and services.

Specifications

A514

The tensile yield strength of A514 alloys is specified as at least for thicknesses up to thick plate, and at least ultimate tensile strength, with a specified ultimate range of . Plates from thick have specified strength of (yield) and (ultimate).^[2][3]

A517

A517 steel has equal tensile yield strength, but slightly higher specified ultimate strength of for thicknesses up to and for thicknesses .

Usage

A514 steels are used where a weldable, machinable, very high strength steel is required to save weight or meet ultimate strength requirements. It is normally used as a structural steel in building construction, cranes, or other large machines supporting high loads.
