HF 1000

Crushed tungsten carbide held in a nickel bronze matrix. The 3 mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF 2000

Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a greater depth of carbide coverage – ideal for high deviation drilling in abrasive formations.

HF 3000

Tungsten carbide inserts set in a powder spray deposit ideal for abrasive formations. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non- magnetic stabilizers.

HF 4000

Tungsten carbide inserts (button type). The inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.

HF 5000

This oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provides excellent bonding properties and greater surface wear characteristics are achieved. Surface hardness levels over 40 HRC. Idear for GEO-THERMAL applications over 350°

HF 6000

This process is a highly automated way of applying hard face and utilizes a combined arc/plasma stream on the work piece surface. This results is low base metal dilution and a dense, uniform coating, the filling medium can be variety of hardfacing consumables.
