High Strength Nickel Alloy Wires Monel K500 Wire UNS N05500 For Vacuum Devices
Nickle Alloy Wires Monel K500 UNS N05500 Vacuum Devices Chemical Production
Welding wires are slim metallic wires that are usually coiled up in spools. These spools are loaded on a wire feeder and the welding wire is continuously fed through a welding gun into the molten weld pool. As a result, arc welding processes that use a welding wire tend to offer higher deposition rates and faster travel speeds, as compared to TIG and Stick welding where the welder must manually feed the filler metal into the weld puddle.
Monel K500, is a age-hardenablenickel-copper alloy that combines the corrosion resistanceproperties of Monel 400 with high strength corrosion fatigue and erosion resistance properties. It is precipitation hardenable through theadditions of aluminum and titanium. The chemica composition of It retains the excellent corrosionresistant characteristics of alloy 400.When compared with Monel 400, it has enhanced strength and hardnessafter precipitation hardening. It has approximately three times the yield strength and doublethe tensile strength of alloy 400.It can befurther strengthened oy cold working before the orecipitation hardening. It should be annealed when welded and theweldment then stress relieved before aging.
Applications:
Typical applications for Monel K500 that take advantage of high strength and corrosion resistance are pump shafts,impellers, propeller shafts, valve components for ships andoffshore drilling towers, bolting, oil well drill collars, andinstrumentation components for oil and gas production.ltis particularly well suited for centrifugal pumps in themarine industry because of its high strength and low corrosion rates in high-velocity sea water.

Machining:
Nickel based alloys can be difficult tomachinine.However, it should be emphasized that thesealloys can be machined using conventional productionmethods at satisfactory rates. These alloys harden rapidlygenerate high heat during cutting, weld to the cuttingtool surface and offer high resistance to metal removabecause of their high shear strengths. The following arekey points which should be considered during machining operations: capacity/tools/positive cut/lubrication.
