UNS N05500 (Monel K500)

Short Introduction:

Monel K-500/W Nr.2.4375/Nickel-Copper Alloy 500/UNS N05500 has 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.

  • Monel K-500 has 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.

  • HY MK-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.
