: To achieve these strength levels, parts are heated to an austenitizing temperature (e.g., 1700°F for D6AC with approval) and then quenched. The specification also allows for marquenching in certain revisions to minimize distortion.

Excess carbon uptake, which can make the surface too brittle. 4. Quality Assurance and Testing ams 2759 2

Before parts are cleared for flight, they must pass a battery of tests: Ams 2759 - 2G | PDF | Secondary Sector Of The Economy : To achieve these strength levels, parts are

AMS 2759-2 is titled “Heat Treatment of Steel Parts, Through Hardening.” Its primary function is to establish the standard process requirements for heat-treating carbon and low-alloy steel parts to achieve high strength and hardness through cross-sectional penetration. Unlike surface hardening methods (such as carburizing or nitriding, which are covered under other AMS 2759 subsections), through hardening alters the core properties of the material. : To achieve these strength levels

The specification mandates a sequence of controlled operations:
