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.
