* Low Dilution* Low Heat Input

GENERAL CHARACTERISTICS

HPP251 tubular hardfacing electrode is designed for use on cast irons, manganese steels, low alloy and carbon steels. Resistant to high abrasive wear and small particle abrasion. Use for applications where impact as well as abrasion are encountered.

TYPICAL APPLICATIONS: Use for severe abrasion and medium impact. This alloy has good hot harness up to 1000o F. Designed for crusher tools, jaw crushers, crusher mantles and liners, hammer mill hammers, bucket teeth and edges. Low amperage requirements result in low dilution and higher hardness.
