HPP 222

HIGH IMPACT HARD-FACING                                   BUILDUP              

HIGH ALLOY ELECTRODE FOR JOINING AND BUILD-UP OF AUSTENITIC MANGANESE STEELS FOR EXTREME IMPACT RESISTANCE

GENERAL CHARACTERISTICS

This high chromium, high manganese alloy is for joining and rebuilding manganese and carbon steel parts.  The high alloy deposits are very tough and will take extreme impact and abrasion conditions.  Has excellent weldability with very low spatter.  Operates easily in all positions. 

TYPICAL APPLICATIONS: For rebuilding and joining austenitic manganese steels and manganese steels to other steel combinations.  Especially designed for high impact applications such as rail frogs and switch points, roller crushers, hammers, shovel tracks.  HPP 222 is also excellent for use as a base for harder overlays.

Welding Parameters

Diameter1/8"5/32"3/16"

Amperage110-135125-190150-250

CurrentAC or DC reverse polarity (electrode+)

Technical Data:

Hardness (as deposited)...16-19 RC

Hardness (as work hardened)......48 RC

Procedure:  Deposits may be placed with either the stringer bead or weaving technique.  This electrode deposits easily in all positions with excellent build-up quality.  Avoid over-heating on manganese steel base metals.  Deposits work harden rapidly.
