Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the adde d advantage of hardness and greater strength. These amplified properties, strength and hardness, are obtained by adding titanium and aluminum to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or aging. When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Monel K-500 has approximately three times the yield strength and double the tensile strength when compared with Monel 400. Plus, it can be further strengthened by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F. The corrosion resistance of monel K-500 is substantially equivalent to that of alloy 400 except that when in the age-hardened condition, nickel monel K-500 has a greater tendency toward stress-corrosion cracking in some environments. Monel K-500 has been found to be resistant to a sour-gas environment. The combination of very low corrosion rates in high-velocity sear water and high strength make monel K-500 particularly suitable for shafts of centrifugal pumps in marine service. In stagnant or slow-moving sea water, fouling may occur followed by pitting but this pitting slows down after a fairly rapid initial attack. Monel K-500® is a nickel-copper alloy with the same corrosion resistance and characteristics as the Monel 400®. The Monel K-500® has a greater strength and hardness then the 400, as a result of added aluminum and titanium. In age-hardened condition, it has greater tendency toward stress- corrosion cracking in some environments. Available forms are Monel K500 Seamless Pipe, Monel K500 Welded Pipe, Monel K500 Seamless Tube, Monel K500 Welded Tube, Monel K500 Round Bars, Monel K500 Wire, Monel K500 Sheet, Monel K500 Plate, Monel K500 Forgings, Monel K500 Pipe Fittings and Monel K500 Flanges.
