Build-up alloys provide filler metal for repairing worn carbon steel, low-alloy steel, or manganese steel parts. The alloys are deposited on the parts in multiple layers to build up the base material of the parts before hardfacing them.

These hardfacing alloys resist abrasion and impact. They are suitable for overlaying surfaces that are exposed to both heavy pounding that can chip or crack the surfaces and gritty materials that can grind the surfaces. These alloys are commonly used for hardfacing equipment such as bulldozer blades, pump housings, and dredge cutter teeth.

These hardfacing alloys resist severe abrasion. They are suitable for overlaying surfaces that are exposed to gritty materials that can severely grind or erode them. These alloys are commonly used for hardfacing equipment such as scarifier teeth, grader blades, and dredge pump casings.

These hardfacing alloys resist wear caused by parts sliding or rolling against each other with little or no lubrication. They are commonly used for creating overlaying surfaces on equipment such as tractor rollers, idlers and drive sprockets, power shovel tumblers, and shafts.
