Characteristics
Excellent mechanical properties from sub-zero temperatures up to about 480C.
Corrosion resistance in an extensive range of marine and chemical environments. From pure water to non-oxidising mineral acids, salts and alkalis.
Applications
Propeller and pump shafts.
Pumps and valves used in the manufacture of perchlorethylene, chlorinated plastics.
Typical application for MONEL K500 which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater.
MONEL K500 is non-magnetic. MONEL K500 should be annealed when welded and the weldment then stress relieved before aging.
High Performance Alloys, Inc. stocks Alloy K500 in a range of sizes including 3/8"-2-1/2" diameter cold drawn, annealed and aged, and 2-3/4"-10" diameter hot finished and aged. Material can be supplied in random lengths, cut to order or machined to your specifications. Machining includes drilling, turning, tapping, threading, CNC shapes, flanges and more.
Machining
Nickel & cobalt base corrosion, temperature and wear-resistant alloys, such as MONEL K500, are classified as moderate to difficult when machining, however, it should be emphasized that these alloys can be machined using conventional production methods at satisfactory rates. During machining these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths.
