1. Introduction AMS 2759/2 is a specialized aerospace material specification published by SAE International. It establishes the engineering requirements for the heat treatment of low-alloy steel parts that must achieve a minimum tensile strength of 220 ksi (approximately 1517 MPa) or higher. This specification is critical for manufacturing highly stressed aerospace components such as landing gear, actuation systems, fasteners, and structural fittings. ams 2759 2
