Waste Gas Fans Achieve Six Times Longer Life Using Tungsten Carbide

Waste gas fan blades are among the greatest wear challenges.


For decades fan manufacturers have tested nearly every material, attempting to get longer life in this application. From diamond plate and AR400, to Chrome Carbide Overlay; they have tried the all.

Processing iron ore, standard waste gas fans last 3 to 4 months before the fan blades were worn to the point it lost effectiveness.




This required downtime changing out the fan rotor and means an expensive rebuild.

ID Fan Blades are subject to continuous small particle abrasion. FLEXWEAR ™ has proven to be an excellent option for increasing equipment life in this demanding application. Many of the major OEM fan manufacturers have seen this type of performance increase. After the blade is welded to the rotor, all seams and edges are hardfaced with Tungsten Carbide to protect these areas.




Utilizing JADCO’s Flexwear ™ Tungsten Carbide increased fan life to 2 years. An increase of SIX TIMES LONGER LIFE.



JADCO FLEXWEAR ™ is created by suspending fine tungsten carbide particles in a powdered nickel matrix. ‘W’ is the atomic symbol for Tungsten, the hardest natural material after diamonds. The symbol ‘Wc’ stands for Tungsten Carbide.



How does FLEXWEAR ™ compare to conventional hardfacing?

This microphotograph at 500 microns shows the bond zone with FLEXWEAR ™. One Inch = 24,500 Microns.





Hand applied hardsurface chrome carbide products are difficult to control and require substantial labor. Comparing the same 0.060” (1/16”) thickness of standard Chrome Carbide hardfacing, FLEXWEAR ™ can provide up to 8 to 10 times longer life.

By rolling the Tungsten Carbide powder into a cloth like material, it can be applied onto complex geometries to combat abrasion, corrosion and erosion challenges. Now you can even protect screens and small perforated plates.

After infiltration brazing onto the fan blades, the Tungsten Carbide particles form a solid dense 70 HRC layer of protection, 0.030” to 0.060” thick.




FLEXWEAR ™ is without question the best option for battling fine particle abrasion.

This fan blade exceeds the Tungsten Carbide cloth width. It is placed onto the fan blade so it doesn’t have a straight seam down the center of the blade. After the blade is welded to the rotor, all seams and edges are hardfaced with Tungsten Carbide to protect these areas.
