| Product Type: Flux-coated Tubular Electrode Description: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. Postalloy® 150HD Vanguard Product Details |

| Product Type: Flux-coated Tubular Electrode Description:Postalloy® Nico-Tek is a superior non-cracking tubular cast iron electrode using state of the art manufacturing and coating technology to produce a welding electrode that is suitable for joining and surfacing various grades of cast iron. Ideal for heavy weldments and filling in deep cavities. Nico-Tek produces a weld deposit with lower weld shrinkage stress which reduces the possibility of weld or heat-affected zone cracking. Nico-Tek has excellent arc-gouging action that penetrates through surface contamination. The easily controlled weld metal results in crack-free, spatter free weld deposits with no undercutting. Base metal should be pre-heated to 400° F (204° C). 1/4" diameter tubular electrode operates at 90 to 120 amps... the same as a standard 1/8" diameter flux coated electrode. Tubular construction allows it to be used at lower amperage. Tubular electrodes resist overheating. Creates dense deposits on dirty, oil soaked cast iron. Low amperage prevents heat rise in casting. Weld layers can be easily filled or machined. Postalloy® Nico-Tek Product Details |
