Austenitic stainless steels (such as the 300 series, e.g., 304, 316, 321, and 347) are non-magnetic and renowned for their excellent corrosion resistance and formability. However, to achieve the mechanical properties required for aerospace applications—specifically stability and strength—these alloys often undergo specific heat treatments.
For heat treatment suppliers, AMS 2759-6 is a cornerstone of Nadcap audits. Auditors will check process records against the standard to verify: ams 2759 6 pdf

is an Aerospace Material Specification titled “Heat Treatment of Austenitic Stainless Steel Parts.” Published by SAE International (formerly the Society of Automotive Engineers), this standard outlines the specific procedures and requirements for thermal processing parts made from austenitic stainless steels.
is a critical aerospace material specification that governs the gas nitriding and heat treatment of low-alloy steel parts. It is designed to enhance surface hardness and wear resistance without the need for traditional quenching, which minimizes part distortion. Core Requirements
