Postalloy® FrogTuff-FCO
Postalloy® FrogTuff-FCO for Weld Repair and Build Up of Manganese Railroad Frogs
Postalloy® FrogTuff-FCO is a high alloy austenitic manganese steel flux-cored welding wire for build-up and overlay of manganese railroad frogs of all types. Produces high-strength, crack-free deposits that are tough and highly resistant to impact and high pressure. Weld deposits work-harden rapidly. The high yield strength reduces mushrooming from impact.
