FCW NM14-G

Tubular wire for gas shielded metal arc hardfacing

Product description

– Tubular wire for gas shielded metal arc hardfacing

– Austenitic manganese steel type alloy used for building up and reinforcing manganese steel castings and wear components

– Excellent work hardening properties. The degree of work hardening is dependent on the amount of impact on the rebuilt component

– The deposit has the same colour as manganese steel

Product application instructions

APPLICATIONS

FCW NM14G deposits a “Hadfield” manganese steel type alloy. It is designed for rebuilding 14 % manganese steel parts. Austenitic manganese steels must be kept cool during welding. Do not preheat. Use intermittent or staggered weld runs and ensure interpass temperature is kept as low as possible. Deposit can be multi-layered.

Examples

Reclaiming crusher jaws and rolls, gyratory mantles, blow bars, swing hammers, manganese dredge components such as buckets and tumblers, railroad sections, bucket teeth and lips, dragline manganese steel shackles and repair of defects in manganese steel castings

Welding positions: FCW NM14G, up to Ø 1.6 mm, is suitable as well for downhand as for positional welding by adapting transfer mode and welding parameters as for solid wires.
