In addition to its excellent mechanical properties such as high strength, corrosion resistance, and non-magnetic properties, Monel K500 alloy also has the same corrosion resistance as Monel 400. It can be used as a pump shaft material and is suitable for working under harsh geological mining conditions of high-sulfur and high-wax oil layers. Since the alloy has no plastic-brittle transition temperature, it is very suitable for various low-temperature equipment. This alloy is mainly used for pump shafts and valve stems, conveyor scrapers, oil well drill rings, elastic parts, valve pads, etc. It is suitable for petroleum, chemical, shipbuilding, pharmaceutical, and electronic sectors.

Chemical composition

The chemical composition of this alloy is roughly the same as that of Monel 400. The biggest difference is that it contains 2.3-3.15% Al and 0.30-1.00% Ti. The organizational characteristics of this alloy are the same as those of Monel 400 alloy except for the precipitation of dispersed Ni3 (Al, Ti) precipitation phase.
