Abramang Mn
Electrode highly resistant to impact
Description & applications
Rutile-basic coated electrode, suitable to surface all pieces subject to high impact. Sometimes used, instead of 18/8Mn, for 13% Mn-steel assembling (Hadfield steels). Frequently used as cushion layer before hardfacing in case of heavy reclaiming. Allows to build up and then to apply abrasion resistant final layers, 1 or 2, using HBA or HB63.
The deposit is austenitic and is exceptionally resistant to impact and wear combined with impact. The addition of Ni and Cr increases the resistance against cracks and abrasion.
General applications: Repairing of used pieces or preventive protection of new pieces used in railway applications (rails, switches, crossings, tongues) in quarries and mines (crusher jaws, excavator and grab teeth, mill hammers, rock crusher).
