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.
AMS 2759-2 is far more than a simple recipe for heating steel. It is a comprehensive quality management system embedded within a process specification. By rigorously defining pyrometry standards, thermal cycles, atmosphere controls, and testing protocols, it mitigates the variables inherent in metallurgical processing. ams 2759 2
These materials are used where a combination of high strength, toughness, and fatigue resistance is essential. AMS 2759-2 is titled “Heat Treatment of Steel
