Product Specification

Material:AISI 4145H, AISI 4145H Mod, AISI 4340, AISI 4140-4142 and Non-magnetic.

Size:Up to 36”


  1. Stabilizer forging/blank, Reamer Forging
  2. Integral Blade Stabilizer
  • Integral spiral stabilizer
  • Interchangeable sleeve stabilizer
  • Straight blade stabilize

All of the connections arestrictly in accordance withAPI Standard, which have stress relief groove and are cold rolled. The flank of thread is phosphatized or plated copper, coated with thread dope and equipped with thread protector. It is mainly the spiral blades (usually three blades, also can be four blades according to customers’ requirements), which rub against the borehole wall. The working surface of the blade is hard faced. The hard facing types we can provide are HF1000, HF2000, HF3000, HF4000, HF5000, and HF6000. It is preferred operation that tungsten carbide inserts are cold inset into the working surface of blades including its bevels. Braze welding tungsten carbide grains are also adopted according to customers’ requirements.


Package:metal frame

Inquiry and order should specify:

l Hole size and type of stabilizer( string or near bits)

2 Material (steel or Non Mag.)

3 OD and ID

4 Connections type and size

5 Fishing Neck OD and length

6 API stress relief groove

7 Open or tight design

8 Right or left hand spiral

9 Hard facing type

10 Float valve and hole

We also can make the Impact value under -20℃ (negative) low temperature according to the requirements of clients. The average impact value is about 30J.(This only for 4145H Mod.)

HF 1000

Crushed tungsten carbide held in a nickel bronze matrix. The3 mm grain size ensures greater concentration of carbidewhich is ideal for soft formation drilling.

Sections through hardfacing.

HF 2000

Trapezoidal tungsten carbide inserts held in a sintered carbidenickel bronze matrix. This will give a greater depth of carbidecoverage – ideal for high deviation drillingin abrasiveformations.

Sections through hardfacing.

HF 3000

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

Sections through hardfacing.

HF 4000

Tungsten carbide inserts (button type). The inserts have beendeveloped to allow cold insertion and maintain close fit.Agreater concentration of inserts on the bottom third of the bladeand leading edge will increase surface contact to reduce wearin highly abrasive formations.

Sections through hardfacing.

HF 5000

This oxy-acetylene process applies tough molten carbideparticles of varying sizes held in a nickel chrome matrix whichprovides excellent bonding properties and greatesurface wearcharacteristics are achieved. Surface hardness levels over 40HRC. Idear for GEO-THERMAL applications over 350°

Sections through hardfacing.

HF 6000

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