AMS 4676 Specification for MONEL K‑500 Bars and Forgings
AMS 4676 provides the specifications for the nickel-copper alloy that can be precipitation hardened, MONEL K-500. The alloy combines the excellent resistance of MONEL 400 to corrosion with significantly greater strength and hardness. It is a sound selection for use in demanding applications.
In addition, the low magnetic permeability of MONEL K-500, as defined by AMS 4676, will remain non-magnetic at cryogenic temperatures as low as 150°F (-101°C). The specific chemistry and processing defined by AMS 4676 assure that the product will exhibit consistent, superior performance in engineering applications.
Applications of AMS 4676 MONEL K‑500
MONEL K‑500 produced to AMS 4676 is specified for components requiring both elevated mechanical properties and corrosion resistance, including:
- Pump shafts
- Oil‑well tools and instruments
- Springs and fasteners
- Valve trim components
- Doctor blades and scrapers
- Marine propeller shafts
What is MONEL K-500 ?
MONEL K-500 is a nickel-copper alloy that offers the superior corrosion resistance of MONEL 400, in addition to the strength and hardness of age hardening. The alloy provides superior mechanical properties with no sacrifice in resistance to corrosive environments, such as those found in the aerospace, marine, oil and gas, and chemical industries.
