Frequently Asked Questions
1. What makes North American Höganäs tungsten carbide superior to conventional steel?
North American Höganäs tungsten carbide is significantly harder and more wear-resistant than steel. With a Vickers hardness of 1,400–1,500 HV (compared to 600–700 HV for hardened steel), it offers up to 10 times the service life in abrasive and high-impact applications. Its high density also provides better vibration damping and penetration capabilities.
2. Can Höganäs tungsten carbide withstand corrosive environments?
Yes. Many North American Höganäs tungsten carbide grades, particularly those with nickel or chromium binders (such as WC-Ni or WC-CoCr), offer excellent corrosion resistance. This makes them ideal for offshore drilling, chemical processing, and marine applications where exposure to harsh chemicals or saltwater is common.
3. How are thermal spray coatings applied using Höganäs powders?
Thermal spray coatings are applied by melting and propelling tungsten carbide powders onto a substrate using high-velocity processes like HVOF or plasma spraying. The result is a dense, well-adhered coating that protects components from wear, erosion, and corrosion, significantly extending their service life.
