A517 / SA517 HSLA Steel Plate
low-alloy (HSLA) steel Product Introduction
ASTM A517 / ASME SA517 is used for high-strength quenched and tempered alloy steel for fusion welding boilers and other pressure vessels. GNEE can provide this alloy steel in the following eight categories: A517GrA, A517GrB, A517GrH, A517GrS, A517GrP, A517GrF, A517GrE, and A517GrQ.
A517 / SA517 implements the American standard ASTM A517/A517M-06.The A517 / SA517 high strength plate specification is a standard specification for pressure vessel plates, alloy steels, high strength quenched and tempered materials used in fusion welded boiler and pressure vessel applications. Under this specification, the thickness of the A517 / SA517 high tensile alloy steel plate is determined Grade selection and mechanical properties.
A517/SA517 low alloy steel sheet has a minimum yield strength of 100 ksi for sheet thicknesses 2.5" and below; A517/SA517 low alloy structural steel has a minimum yield strength of 90 ksi for sheet thicknesses over 2.5".
