This standard establishes uniform physical item identification marking in constantly recurring symbols for selected iron and steel products which are procured and issued for Government agencies. Shipment and inspection acceptance marking are not within the scope of this standard.
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.

This recommended practice provides guidelines for the establishment of an induction hardening process for steel components. It is intended to be used as a guide for designers of induction hardened parts, for process auditors, and for purchase specifications and/or process sheets as applicable. Induction heat treatment is intended for hardening of only selected areas of plain carbon or alloy steel components. A prior heat treatment may be specified for improved response of the overall component to induction hardening, or for control of properties in the balance of the part. AMS 2759 is recommended for such prior heat treatment.
