EB Nickel Alloy UNS N05500 Monel K500 Ball
Alloy 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. 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.
1. Monel is widely used in chemical, pharmaceutical, maritime, oil, textile and paper industries.
2. It is highly resistant to (caustic) alcaline solution, sea water and diluted sulphuric acid.
3. Monel-K500 is often used when higher hardness and resistance are needed.
