HPP 225M

PREMIUM HARD-FACING BUILD-UP                                                        

GENERAL CHARACTERISTICS

HPP225M is an outstanding OPEN ARC WIRE. HPP225M deposits are excellent work hardening high chromium austenitic manganese steel alloys. It can be used for build-up or overlay on manganese steel, carbon and low alloy steels. It can also join austenitic manganese steel to carbon steel and low alloy steel. Deposits are very tough and work harden rapidly under high impact.

TYPICAL APPLICATIONS: Crusher rolls & cones, hammer mill hammers, impactor bars, railroad frogs & crossings.
