Powders, Hard Facing

  • Designations: Hard Facing Materials
  • Description: Hardfacing consists of depositing a layer of wear resistant material over a common metal in order to improve its service life.

    Depending on the application, hardfaced parts in general can last 3 to 10 times longer than an untreated part and costs a fraction of the prices if the same part was made entirely of the hard metal.

    The material of choice to increase wear protection and useful life is Tungsten Carbide (WC) as its hardness is much higher than most metals.

    Hardfacing can save your company time and money by:

    • Extending the useful life of your hardware.
    • Selectively applying the hard alloy only where it is necessary instead of making entire pieces from very hard materials.
    • Reduces inventory costs by requiring fewer replacement parts on hand.
    • Reduces equipment downtime.
