Hardfacing Electrodes

Super-Mn is an electrode depositing high manganese steel weld metal. The weld metal possesses excellent toughness and work hardens under impact. The deposit exhibits an austenitic structure and is ideally suited for re-surfacing austenitic manganese steel components like crusher jaws, hammers, etc. for resistance against wear by impact and abrasion.

1. Ensure the surface to be built- up is free of all contaminants.

2. Remove by grinding any work hardened zone. A magnet can detach a work hardened zone.

3. Ensure the electrodes are dry. Re-dry the electrodes at 200-250°C for one hour.

4. When welding on austenitic manganese steels, restrict heat input by :

a) Short arc;

b) Stringer bead;

c) Deposits of short lengths and thickness;

d) Intermittent welding;

e) Keeping base material partly immersed in water.
