Parts shall be tempered immediately after quenching to prevent delayed cracking.

Mastering AMS 2759/2: The Aerospace Standard for Ultra-High-Strength Low-Alloy Steels

is the definitive aerospace material specification governing the thermal processing of low-alloy steel components engineered to achieve an ultimate tensile strength of 220 ksi (1517 MPa) and higher . Maintained by SAE International , this sub-tier specification must always be executed in tandem with the overarching parent standard, AMS 2759 , which outlines foundational requirements for steel heat treatment. ams 2759/2

Unless otherwise specified in the part drawing or purchase order, the requirements of this specification take precedence over the heat treatment instructions provided by the steel supplier.

This specification covers the engineering requirements for the heat treatment of steel parts. It applies to all types of steel parts, including carbon steel, alloy steel, and stainless steel, requiring specific mechanical properties obtained through thermal processing. Parts shall be tempered immediately after quenching to

Based on standard aerospace engineering references, refers to the specification for Heat Treatment of Steel Parts .

It provides specific parameters for thermal processing, including: Hardening and tempering temperatures. Quenching media and procedures. Unless otherwise specified in the part drawing or
