Product Reference View detailed information about Postalloy® Hardfacing Products

Postalloy® 150HD Vanguard is a tubular hardfacing electrode that provides a dense, heterogeneous deposit of vanadium - tungsten carbides, along with other elements to enhance wear resistance, resulting in a very good combination of abrasion and impact resistance. This makes it superior to chromium carbide hardfacing alloys and almost equal to tungsten carbide in hardness at half the weight. Postalloy Vanguard 150HD is not a replacement for tungsten carbide overlays. However, it is a good alternative to tungsten carbide hardfacing alloys when they are too expensive or when MIG carbide embedding is not available or impractical. Unlike straight tungsten carbides, which are heavy and forced to the bottom of the weld puddle, the composition of Postalloy®150HD Vanguard is ideally balanced to provide a uniform distribution of vanadium - tungsten carbides throughout a tough steel matrix that takes more impact than both chromium and tungsten carbides. Also, it provides a very consistent wear rate and is designed for multiple re-applications. An excellent choice for many different hardfacing applications including mining, construction, recycling, dredging, forestry and sugar industries.
