| Page Count: | 12 |
scope:
MPAPS A-40 covers the following case hardening processes for ferrous parts:
A. Carburizing and Carbonitriding - thermochemical processes of case hardening that involve the diffusion of carbon or carbon and nitrogen into the surface of ferrous materials at elevated temperatures
B. Nitriding and Ferritic Nitrocarburizing - thermochemical processes of case hardening that involve the diffusion of nitrogen or nitrogen and carbon into the surface of ferrous materials at low temperatures between 930OF to 1050 OF
Restricted Chemical Substances
All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.
APPLICATION
This specification covers diffusion based surface hardening of ferrous parts for the purpose of enhancing their fatigue, wear and/or corrosion resistance properties.
