Uns N05500 Monel Nickel Alloy 500 Wire With Outstanding Corrosion Resistance
Monel 500 WIRE
Descripition:
MONEL®alloy K-500 (UNS N05500/ W.Nr. 2.4375) is a nickel-copper alloy which combines the excellent
corrosion resistance of MONEL alloy 400 with the added advantages of greater strength and hardness.
The increased properties are obtained by adding aluminum and titanium to the nickel-copper base,
and by heating under controlled conditions so that submicroscopic particles of Ni 3 (Ti, Al) are precipitated
throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or aging. The composition of the alloy is given in Table 1. Typical applications for MONEL alloy K-500
products are chains and cables, fasteners and springs for marine service; pump and valve components for
chemical processing; doctor blades and scrapers for pulp processing in paper production; oil well drill
collars and instruments, pump shafts and impellers, non-magnetic housings, ety lifts and valves for oil
and gas production; and sensors and other electronic components.

| 1(25.4)and over | 130(895) | 85(585) | 20 | 250 | 24has approximately twice the tensile strength and triple the yield strength of Alloy 400. The strength of Alloy K-500 is maintained to 1200 degrees Fahrenheit, but stays ductile and tough down to temperatures of -400 degrees Fahrenheit. Alloy K-500 also stays non-magnetic to -200 degrees Fahrenheit. | ||
Additional characteristics of Alloy K-500 include outstanding corrosion resistance in a wide range of chemical and marine surroundings, from salts and alkalis, non-oxidizing acids to pure water. Alloy K-500 is non-magnetic and spark resistant. It is also recommended that Alloy K-500 be annealed when it is welded and that any weldments be stress relieved prior to aging.
