The specification outlines the following heat treatment processes:
AMS 2759/2 specifies the following requirements:
Parts must conform to specific hardness values that correlate with the required high tensile strength. ams 2759/2 pdf
This text is a summary for informational purposes. It does not replace the official SAE AMS 2759/2 standard document. For engineering, manufacturing, or auditing decisions, please purchase and reference the latest revision of the PDF directly from SAE International.
The standard outlines precise procedures for several critical stages of the heat treatment cycle: Key Technical Requirements After heat treatment, parts must
Furnaces and equipment must meet SAE AMS-H-6875 standards. Process Steps:
Alloys like Aermet 100, formerly part of this spec, are now covered under AMS 2759/3 . Key Technical Requirements Key Technical Requirements After heat treatment
After heat treatment, parts must undergo testing to verify compliance:
Parts must be clean and free of oil, grease, scale, or other contaminants prior to heat treatment. Surface contaminants can react with the metal at high temperatures, leading to intergranular oxidation or surface defects.
AMS 2750 (Pyrometry) for furnace uniformity and sensor calibration. Surface Protection: Guidance on atmosphere control to prevent decarburization or scale. Why it matters: In aerospace manufacturing, there is zero room for error. Following AMS 2759/2 ensures that critical components—from landing gear to structural fasteners—meet the fatigue life and stress-corrosion resistance required for flight safety.
