Hard Facing

Products

MRO Electrodes
MetaLine®
Brazing Alloys

HF-2

Extremely high touchness, resistance to high impact, friction and abrasion

Alloy base

Mn, Cr, C, Fe

Special Features

  • High abrasion resistance after work hardening in service.
  • High recovery of weld metal.
  • Extremely high toughness.
  • Single welding alloy for cushioning and final layer.
  • Resistance to moderate impact, metal-to-metal wears, two and three body abrasion.
  • Deposits exhibit rapid work hardening while in impact services.

    • Recommendations

    Proving efficient on carbon/alloy steels as cushion layer prior to hard facing. This alloy weld suitable for build up and over lay of low, medium carbon, low alloy steels and manganese steel including hard field manganese steels.

    Princial Applications

    Austenitic manganese steel parts, railway point's crossings, joints, crushing hammers and mantles, bucket teeth, mill hammers, pressure pilling hammers.

    Procedure

    Clean weld area and remove worn out or fatigued metal. Always use the short, stringer beads. Temperature of manganese steel should not exceed 250oC. Cool slowly to avoid cracking.
