Product Code:SAE AMS2759/6
Title:Gas Nitriding and Heat Treatment of Low-Alloy Steel Parts
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope: This document specifies the procedure and requirements for heat treating low-alloy and tool steels and for their subsequent gas nitriding by the use of raw or dissociated ammonia. Specific process parameters are given for Nitralloy 135M, Nitralloy EZ, Nitralloy N, 4140, 4340, D6AC and H11 steels. Additional alloys and steel families (e.g., stainless steels) can also be nitrided using parameters acceptable to the cognizant engineering organization.
