HF-1

Resists severe impact and friction

Alloy base

Fe, Cr, Mn, C

Special Features

  • Suitable for build up of low and medium carbon and alloy steel.
  • Superior machinability.
  • High toughness and resistance to deformation.
  • It can be flame hardened.
  • The weld deposit exhibits resistance to impact.
  • All positional welding in rapid deposition.

    • Recommendations

    Tough machinable build-up and over lays for wear resistance to severe impact on ferrous parts subjected to heavy shock loading and pounding in service. Especially required for build-up of low medium carbon and alloy steels. A versatile field welding alloys having completely machinable characteristics.

    Princial Applications

    : Rollers, sprocket wheels, crane wheels, pinions & gears, wobblers, couplers in steel plants and sugar plants, girth gears, rollers of kiln tyres, excavators, chassis and mixer blades.

    Procedure

    Clean weld area and remove the fatigued material. Use short to medium arc and use stringer beads. Long weld deposits may be laid without danger of cracks. Avoid excessive heat build-up to control cracks.
