HPP 253

HIGH TEMP ABRASION                                          HARD-FACING

ULTIMATE ELECTRODE FOR ABRASION, IMPACT AND HEAT RESISTANCE IN SEVERE ENVIROMENTS

SPECIAL CHARACTERISTICS

* All position* Moisture resistant Coating* High Efficiency

* AC/DC Operation* High Deposition* Requires Low Amperage

* Low Dilution* Low Heat Input

GENERAL CHARACTERISTICS

HPP253 weld metal is composed of complex carbides of chromium, tungsten, molybdenum, columbium and vanadium.  This results in a deposit highly resistant to fine particle abrasion and erosion at temperatures up to 1500O F.

TYPICAL APPLICATIONS: 

Conveyors for hot coke, slag and cement.  Kiln grates, crushers and other equipment subjected to abrasion and erosion at elevated temperatures.  Very good for extreme abrasion with impact such as crusher cones and mantles in taconite crushing operations.  Excellent for feed chutes handling hot abrasive materials.
