| Low Heat Build-up on Manganese Steel |
| This is a low heat input electrode suitable for surfacing,
building up and joining of austenitic manganese
steels of plain & alloy types. The austenitic deposit
is more resistant to cracking, deformation and heat
embrittlement. The deposit is tough to witbstand metal
to metal impact. It resists wear under rolling abrasion at
high contact pressures. |
| |
| ALLOY BASE |
| Fe, C, Mn, Ni |
| |
| SPECIAL FEATURES |
- Graphite free coating avoids carbon pick-up
- Deposit gives high strength, combined with excellent
resistance against impact
- Smooth are, fine ripples and a fluid but controlled
slag, which is easily detachable
|
|
| APPLICATIONS |
| Manganese steel shovel bucket teeth & lips, pulverizing
hammers, beaters, grinding ring & rollers, gyratory
crusher mantle and liners, cone and ring, jaw crusher
plates etc. |

WELDING PROCEDURE
- 14% Mn steel should never be preheated for
welding
- Welding should be done in stringer beads directing
the towards the weld pool
- Heat input to the base metal should be kept minimum,
if required skip welding/back step welding can be
adopted
- The weld bead must be peened with ball pen hammer
immediately after welding
- Quenching has no adverse effect on welding and
should be adopted whenever possible after slag
removal and peening. If possible the Mn steel job
can be submerged in water during welding
