- Metco 8226 is an iron-based alloy specifically designed to produce overlays using GMAW process that replicate the microstructure of tungsten carbide PTA overlays. - Metco 8226 grows extremely hard molybdenum boride (MoB) particles homogeneously throughout the entire weld bead. These MoB particles are harder and smaller than the tungsten carbide hard phase in PTA weld overlays, a characteristic that enhances impact resistance. - Metco 8226 overlays are suggested for use in any application where wear resistance to gouging or high-stress abrasion is required.
