Monel K500 alloy addition to high strength, corrosion resistance, non-magnetic and other excellent mechanical properties, Monel 400 also has the same corrosion resistance. Serve as a shaft material, the more difficult for high-sulfur, high wax layer of the geological mining conditions. Since the alloy is not plastic - brittle transition temperature, it is very suitable for a variety of cryogenic equipment. This alloy is mainly used for pump and valve stem, conveyor scrapers, oil well drilling rings, elastic components, valves, pads, etc. For petroleum, chemical, shipbuilding, pharmaceutical, electronics department.

■ chemical composition

The chemical composition of the alloy Monel 400 with the same general, the biggest difference is with 2.3-3.15% and 0.30-1.00% of the A1 Ti, characteristic of this alloy in addition to a dispersion of Ni3 (A1, Ti) phase precipitation precipitation outside , the other with the same alloy Monel 400.

Elements (%) Ni:> 63; Cu: 27/33; Mn <1.5; Fe <2; Si <0.5; A1 2.3/3.15; Ti0.35/0.85

                             

■ mechanical properties

     The alloy is not plastic - brittle transition temperature, making it ideal for a variety of cryogenic equipment, welding can increase the strength of the alloy, but lower alloy plasticity. Therefore, in order to maintain a high plasticity, Monel K500 alloy heat treatment after welding required.

Tensile strength (MPa) Yield strength (MPa) Elongation (%) Hardness (HB)

935/1275 655/1103 10/20 255/370

■ corrosion resistance

    General solution state Monel 400 Monel K500 alloy patience with basically the same, therefore, the corrosion resistance of Monel 400 can be applied to the data completely Monel K500 alloy. As the flow of seawater in the alloy corrosion rate and the low-alloy high-strength, therefore, the alloy particularly suitable for seawater corrosion resistant centrifugal pump shaft.
