What is cemented carbide?

Carbide consists of tungsten carbide as a hard substance and cobalt as a binder metal. The cemented carbide is extremely hard, about 2600 Vickers, many times harder than the hardest possible hardened wear steel (about 650 Vickers) and also harder than most rock minerals, including quartz and porphyry, which are very common minerals in our Nordic roadways. On the mineral hardness scale Moh, where diamond is the hardest (10), quartz and porphyry are at 7 Moh and the cemented carbide is about 9 Moh, in other words harder than the hardest in the road surface, which gives carbide plows a very long wear time. The hardest wear steels in HBW600 are at about 5.5 Moh, ie softer than the material in the road surfaces, which means that the wear steel wears quickly.

 Carbide has for long been used in mechanical processing, for example in concrete drills. Now the cemented carbide has also begun to have an impact on snow removal. More and more people are switching to plows with cemented carbide instead of hardened wear steels. The many advantages of cemented carbide edges simply provide better economy. More kilometers of plowing per crown for the plow edges, less overhead on steel replacements and reduced risk of damage to the plow that arises due to worn steel and incorrect plow settings. All in all, great advantages in an industry with a constantly squeezed economy.
