Stabilizers are made from premium chrome molybdenese alloy steel (except for non-magnetic style), heat treated by special procedure and obtain expected hardness, strength and impact ＆#118alue properties. all threads are made strictly in accordance with API specification. The hard banding of stabilizers employ "pressed in" Tungsten Carbide alloy buttons or other anti-wear materials. All stabilizers should be ultrasonic tested.
Our company also provides non-magnetic stabilizers.

Our company manufactures four kinds of stabilizers as below:
1 Integral spiral stabilizer (premium chrome molybdenum alloy steel and non-magnetic low carbon chrome manganese alloy steel) 
Integral Spiral Stabilizers are made from AISI 4145H Modified alloy steel or Non-magnetic alloy steel, the pressed button type or applied Tungsten Carbide hard banding on the blade facing are available. The Non-magnetic stabilizers have special hard banding on the spiraled blade surface that the magnetic properties have been eliminated.

2 Interchangeable sleeve stabilizers
The interchangeable sleeve stabilizers are made of 4145H alloy steel. Heat treated to 285-341 Brinell Hardness and 54 Joules minimum impact ＆#118alue. All physical properties would be guaranteed 1" below the surface. The kind of stabilizer is constructed of two pieces which are jointed by the center connection and one sleeve. Every stabilizer is equipped with a certain size of sleeve.

3 Sleeve Stabilizer
The sleeve stabilizers are made of 4145H modified alloy steel which is fully heat-treated to 285-341 Brinell Hardness and 54 Joules minimum impact ＆#118alue. The stabilizer consists of a one piece of body and a sleeve which is jointed, the sleeve can be changed after fretted

4 Integral Straight Rib Stabilizer
The straight rib stabilizers are made of AISI 4145H alloy steel by one piece of integral bar. Every stabilizer has four straight ribs that pressed Tungsten Carbide buttons or other types of hard facing are located on the surface of the ribs. Ultrasonic inspection is performed on each stabilizer.
