Monel® K-500 Bar
Nickel Alloy 500 and Monel® K-500, commonly known as UNS N05500, is a nickel-copper based alloy which combines the excellent corrosion resistance of Nickel Alloy 400 with added advantages such as greater strength and hardness, making it superior to the other nickel-copper based alloys. This is achieved through the addition of titanium and aluminum which is added into the overall composition of the material. It has approximately twice the tensile strength and triple the yield strength of Nickel Alloy 400. This superior strength is maintained up to 1200° F, and conversely stays ductile and tough down to temperatures of – 400° F. Another advantage of Nickel Alloy 500 is that it stays non-magnetic at temperatures down to – 200° F which is ideal for applications where electronics are attached or in close proximity to the material where a magnetic field can be a disruption, such as downhole or tubing. Additional characteristics of Nickel Alloy 500 include spark resistance and outstanding corrosion resistance in a wide range of chemical and marine surroundings, including salts, alkalies (or acid-like substances), and non-oxidizing acids. NSA stocks a full range of Nickel Alloy 500 sizes and finishes; we receive our material from the mill age hardened (or aged) which has higher physicals than materials supplied in the annealed condition.
Nickel Alloy 500 Rev. G, QQ-N-286G, is an approved Federal specification, generally used in naval applications. This specification calls for the material to be raised to an even higher level of standard than the basic Nickel Alloy 500. It must be produced either by an electric arc furnace, or a vacuum induction furnace. After production the material will be further refined to pass the slow strain rate tensile test (SSRTT). In retrospect, Nickel Alloy 500 Rev. G is requested for applications generally because it is not susceptible to intergranular cracking.
Industries that use 500 include:
- Chemical processing
- Marine engineering
- Oil and Gas extraction
Products partially or completely constructed of 500 include:
- Centrifugal pumps
- Oil and Gas production components
- Propeller shafts
- Pump shafts
- Valve components
