Postalloy® A-Max Wear Plate was designed to overcome the labor-intensive cost of hardfacing.

  • Small and light weight, the wear plate can be installed by any maintenance any position.
  • It can be quickly installed and less expensive than hardface welding…can be installed 10 times faster.
  • Less welding means less heat…less warpage and distortion.
  • Can be Flame or plasma cut…can be easily cut to any size.
  • Can be bolted or welded in place.
  • Installs with tack welds using Postalloy® 301 or 305 electrodes, or Postalloy® 301-FCG or 3044-FCG wire.
