Scope

Purpose This document specifies the procedure and requirements for gas nitriding low-alloy and tool steels by the use of raw or dissociated ammonia. Additional alloys and steel families (e.g.@ stainless steels) can also be nitrided using parameters acceptable to the cognizant engineering organization. Application The nitriding process described herein has been used typically for producing a wear resistant and fatigue resistant surface on steel parts@ but usage is not limited to such applications. This process only applies to gas nitriding. Other processes@ such as salt bath nitriding perAMS2753@ ion nitriding per AMS2759/8@ automated gas nitriding controlled by nitriding potential per AMS2759/10@ automated gas nitrocarburizing by potential per AMS2759/12 and gas nitrocarburizing per AMS2757@ are not included. The provisions of this specification revision shall become effective 90 days after publication. Classification Processes covered by this specification are classified as follows: Class 1: Two-stage nitriding with maximum applied white layer of 0.0005 inch (13 pm). Class 2: One-stage nitriding with a maximum applied white layer of 0.001 inch (25 pm). If no class is specified@ either Class 1 or Class 2 may be provided.
