Postalloy® PS-150 is a tubular metal-cored hardfacing wire 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 that is superior to chromium carbide hardfacing alloys. Almost equal to tungsten carbide in hardness, and half the weight. Postalloy Vanguard PS-150 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® PS-150 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. Provides a much more consistent wear rate and is much more receptive to multiple re-applications. Used for many different hardfacing applications in
mining, construction, recycling, dredging and forestry and is ideal for hammer applications (martillo), such as fribrizor hammers, sugar mill hammers, debarking hammers and shredding hammers.
