Railroad Engineered Hardfacing and Build-Up Welding Alloys
POSTALLOY® Hardfacing Alloys for Railroad Frogs, Switches and other track and rail components.

POSTALLOY® Hardface Welding Alloys for rail and track repair are specially engineered to ensure maximum service life of hardfaced surfaces. Hardface Technologies offers a variety of hardfacing alloys that become harder and tougher during use to withstand the constant pounding of railroad cars. Benefits of POSTALLOY® Hardfacing Alloys include:

  • Excellent wear and impact resistance
  • Easy weldability
  • Provide support for wheels and passageways for their flanges

Hardface Technologies has great support too! For complete application procedures please contact Postle Industries at (216)265-9000.
