Key features

Diversified Grade Selection: Threeeee grades (LN-103/LN-203/LN-303) with different hard phase materials to match various abrasion and cutting working conditions and meet different downhole tool surfac

Excellent Wear & Impact Resistance: Uniform distribution of hard phase inside the rod. The surfacing layer features strong wear resistance and good impact toughness, effectively extending the service

Stable Welding Performance: Sintered integrated forming structure. Stable combustion during oxy-acetylene surfacing, less splashing, easy operation, and forms a dense, wear-resistant coating.

Product Q&A

Q:What are the carbide sintered welding rods used for?

For hard-surfacing worn parts in petroleum, mining, geology, and construction. Applied to drilling tools, milling shoes, hydraulic cutters, etc.

Q:What is the applicable welding method?

Oxy-acetylene flame surfacing is recommended. The rod burns steadily with less spatter during operation.

Q:What are the differences among LN-103, LN-203 and LN-303?

LN-103: Cast tungsten carbide + spheroidal alloys, great for heavy abrasion conditions LN-203: Spheroidal tungsten carbide + spheroidal alloy, balanced wear resistance and impact resistance LN-303: Spherical high-entropy alloy, excellent high-temperature wear and corrosion resistance

Q:How to select the proper grade among LN-103/LN-203/LN-303?

Choose based on your working temperature, abrasion strength, and corrosion requirements. Contact us to get a professional-grade recommendation.
