M50NiL steel is a case-hardening steel used for aeroengine bearing with a tough core [1, 2]. Traditional surface hardening method, such as gas carburizing , plasma nitrocarburizing [4,5
Anyone with access to GE EMPIS (Even an old one?) - Metal M50 NIL (AMS 6278) is a high-performance bearing steel. Is this part used in a rolling element bearing? RE:Anyone with access to GE EMPIS (Even an old one?) metengr (Materials) 20 Jan 16 13:05. Is this material specification for a part from a steam turbine, pump or gas turbine?
Bearing steel is a kind of steel to used for ball bearing, roller bearing and bearing sheath. Bearing steel can be broadly divided into High-carbon chromium bearing steel, Carburized Bearing Steel,Stainless bearing steel,High temperature bearing steel,etc.. High-carbon chromium bearing steel,also named fully quenching steel for the character of high hardness (HRC 58-60), is an
EXPERIMENTAL INVESTIGATION RESULTS OF A HYBRID For the bearing raceways M50NiL material as per AMS6278 was used. The cage is made out of AMS6414 steel, bearing a sliver plating in accordance with AMS2412. The cage/ball assembly in Fig. 3 shows the 22.225 mm (7/8) size ceramic balls after the test run. The under-race lubrication is ensured by 6 radial oil grooves in
Heat Treatment of Bearings Heat Treating of Irons and The choice of heat treatment depends on the service requirements of a given bearing and how the bearing will be made. This article describes the design parameters, material characteristics required to sustain performance characteristics, metallurgical properties, and dimensional stability.
This papers reviews some of the key parameters in the production and development of the aircraft bearing steels M50 (AMS 6191) and M50NiL (AMS 6278). The

Materials New Hampshire Ball Bearings, Inc.Standard and Advanced Bearing Materials. 52100 chrome steel, 440C stainless steel, and M50 tool steel are the most common materials used in rolling element bearings, as they are suitable for most applications. Extreme operating conditions often require the use of more advanced alloys such as BG42®, M50 NiL, and Cobalt-based alloys.

Relation Between Residual and Hoop Stresses and steel for use as a race material for rolling-element bearings. This steel, designated M50 NiL (AMS 6278), has reduced carbon content (from 0.8 to 0.13 percent) to improve the fracture toughness of the core and 3.5 percent nickel is added to stabilize the austenite and prevent the formation of excessive amounts of ferrite and retained austenite.
