Steel Bars and Forgings 0.50cr (0.98-1.10c) (SAE 50100) for Bearing Applications

2003-09-05
CURRENT
AMS6442G
This specification covers a low-alloy steel in the form of bars, forgings, and forging stock. Primarily for parts of small cross-section, such as needle bearings, requiring a through-hardening steel usually with hardness of approximately 60 HRC and subject to very rigid inspection standards.

Gas Nitriding and Heat Treatment of Low-Alloy Steel Parts

2002-03-14
HISTORICAL
AMS2759/6A
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.
