Product Description

HARDFACE NM14-0 x 1.2mm

CLASSIFICATION

EN 14700 T Fe9

DESCRIPTION

  • Tubular wire for self shielded metal arc hardfacing  
  • Austenitic manganese steel type alloy used for build 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  
  • Chromium and nickel free variant of Hardface NM-O  
  • The deposit has the same colour as manganese steel 

APPLICATIONS

Hardface NM14-O 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.
