AWS A5.13 : EFeMn-C


Rutile-basic coated electrode, suitable to surface all pieces subject to high impact. Sometimes used,
instead of selectarc 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).
