The specification, published by SAE International , is the definitive aerospace standard for the heat treatment of low-alloy steel parts requiring high strength. Specifically, this "slash sheet" governs parts that must achieve a minimum ultimate tensile strength (UTS) of 220 ksi (1517 MPa) or higher . Scope and Purpose
The standard outlines a structured process to ensure material integrity and performance:
Strict controls are placed on furnace atmospheres (e.g., using Argon, Vacuum, or Hydrogen) to prevent surface contamination like decarburization or carburization. Quality and Testing
This specification must be used in conjunction with the AMS 2759 General Requirements document.
AMS 2759/2 is a widely adopted specification for the heat treatment of low-alloy steel parts. The document provides guidelines for the heat treatment processes, inspection, and testing of low-alloy steel parts to ensure they meet the required mechanical properties and microstructure.
