Postalloy® FrogTuff
Ideal for use on manganese steel. Under severe impact, such as hammering or pounding, deposits quickly become tougher and harder. Produces high-strength, non-cracking deposits that are tough, ductile and work-harden rapidly. The high yield strength reduces mushrooming from impact. Postalloy® FrogTuff may be used alone, as a combination build-up and hardfacing alloy, or used as a build-up and cushion prior to overlaying.
Postalloy® FrogTuff is an all-position crack-free electrode for joining or overlaying for high impact. It operates on either AC or DC reverse; the arc is smooth and stable with low spatter loss. Slag removal is easy.
