Tough austenitic manganese based steel welding allot to resist high impact

Alloy base

Cr, Mn, C, Fe

Special Features

  • A tough austenitic anti wear welding alloy for building up and overlaying of high manganese steels.
  • Deposits are tough and work hardened under repeated and pounding loads.
  • Best suitable for impact, shock and hammering
  • Non-cracking and long lasting.
  • Excellent abrasion resistance in the work hardened conditions.
  • Resists multi wear like abrasion and high impact.

    • Recommendations

    Use this alloys as a cushioning layer for hard surfacing. Basically a ferrous base electrode with additions of other alloying elements like nickel, manganese and other to improve inherent characteristics of welding.

    Princial Applications

    Crushers, bucket teeth, wear plates sprocket, hammers, sprockets, chain links, crusher mantles, crusher jaws, shovel track pads, hammer mills, wobblers, buckets lath bars arid keys etc.

    Procedure

    Clean and gouge/grind out worn out or fatigue metal. Use short arc skip & staggered welding sequence. The temperature of the manganese steel should be kept below 200oC. Cool slowly.

    Hardness

    180-220 BHN (AS Deposited)
    400-450 BHN (Work Hardened)

    Recommended Amperage AC/DC (+)
