Z- 2411 REBUILDING & HARDFACING TOUGH AND HARD Z-2420
Work hardening SURFACING

Description: Description:
Cold work hardening Mn austenitic electrode. All purpose alloy for rebuilding and An electrode for components subjected to severe wear conditions. The metal
joining carbon and 14% manganese steels. For buffer layer prior to hard facing. is crack and pore free and resistant to impact stress. Can be machined only by
grinding. A buffer layer of Z-307HR electrodes is only required when welding
Uses: difficult to weld steels.
For filling and coating Carbon and Manganese steel, Hadfield steel, armored steel
and hard-to-weld steel. For use with items such as railroad wheels and tracks, Uses:
crasher plates, pumps, dredger teeth, hammers, conveyor belts, agricultural • Excavator parts.
