HF-3

Resistance to low stress scratching and high stress grinding abrasion

Alloy base

Fe, Cr, Mn O

Special Features

  • Smooth weld bead appearance.
  • Tough and porosity free
  • Superior resistance to abrasion with moderate impact also.
  • Best weldability.
  • Deposits exhibit uniform distribution of carbides in a hard martensitic form.

    • Recommendations

    For steel parts encountering severe abrasive conditions. Best recommended for mining equipments, cement plants and construction industries. Used for abrasion resistance over lays on plain carbon & had field manganese metal and gray cast irons. Deposits provide very low coefficient of friction.

    Princial Applications

    Buckets (pads, lips, teeth), jaw crusher, crapper bead, plough shears, road rip, pug mill screws, fan blades, crusher mantles, pulverizer hammers etc.

    Procedure

    Clean weld area & remove fatigue material by gouging. Use stringer beads and skip & stagger weld. To build up more than one layer deposit a cushion layer have HF 1 Or HF 7 or AS-4. The temp of the base metal should not exceed 250oC to avoid heavy cracks.

    Hardness

    57-63 RC
