Advantages and Disadvantages of Monel Alloy R405

    Advantages:

  • Machinability: Sulphur causes material to become easier to machine due to this it has been added into the composition of steel.

  • Corrosion Resistant: Very high durability in regions where there’s high corrosion potential.

  • High Strength: It has the capability of retaining high strength in high temperatures.

  • Versatile Applications: Suitable for construction industry, automotive industry, aerospace, power plant and other industrial sectors.

    Disadvantages:

  • Cost: Pricier as some components are introduced in addition to general work and additional steps are made.

  • Sulfur Addition: In turn, this reduces the ductility of the material due to the dislocation of atoms that are formed during the rolling process.

  • Weldability: Lower weldability capacity as compared to Monel 400.

  • Availability: Not as easily obtainable as some other Monel grades.
