Ams 2759 2 Free May 2026

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.

| Property | Requirement | |----------|--------------| | Tensile Strength | ≥ 220 ksi (1517 MPa) | | Yield Strength (0.2% offset) | Typically ≥ 180 ksi (varies by alloy) | | Elongation in 4D | ≥ 6% (typical minimum) | | Reduction of Area | ≥ 20% (typical minimum) | | Hardness (HRC) | Approx. 48–55 HRC (depending on exact strength level) |
