This alloy has the following properties:

Monel K-500 is a corrosion resistant alloy with the same corrosion resistance as Monel 400. It has high mechanical strength and hardness. The alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, as well as in hot concentrated alkali solution. At the same time, it is also resistant to the corrosion of neutral solution, water, seawater, atmosphere, organic compounds, etc. An important feature of the alloy is that it does not produce stress corrosion crack and has good cutting performance

The application fields of Monel K-500 include:

Monel K-500 alloy is a multi-purpose material, which can be applied in many industrial fields:

1. Used for manufacturing turbine blades and gas turbine blades with working temperature below 750 ℃ on Aeroengine

2. Used to manufacture fasteners and springs on ships

3. Sulfuric acid and hydrochloric acid environment

4. Pump shaft and valve parts on chemical equipment

5. Pump shaft and propeller of equipment used in sea water

6. Scraping blade on papermaking equipment
