HF 1000
Crushed tungsten carbide held in a nickel bronze matrix. The 3mm 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. Surface hardness levels over 40HRC. Ideal for GEO-THERMAL applications over 350°C.
HF 7000
HF7000 Laser hardfacing produces impervious overlays tailored for specific wear applications in corrosive or non-corrosive environments. The metallurgical bond between the overlay and the part provides high resistance against interface corrosion and high bond strength. The low-heat input of the laser-process allows for the deposition of crack-free overlays for wear protection.
