For Oxy-Fuel Braze Welding Broken and Fractured Gray and Medium-Strength Alloyed Cast Irons
Xuper 146 XFC ®
BRAZING • Recommended for use on cast iron where color matching isn't important • Highly active flux promotes eas of wetting and excellent bonding • Deposits are easily machined or drilled
DESCRIPTION
PROCEDURE FOR USE
Xuper 146XFC is a copper-base, flux-coated brazing rod for repairing cracks and buildup repairs of cast irons when color matching is not important and when easily machined and drilled deposits are required. The highly active flux promotes ease of wetting and excellent bonding.
Preparation: Clean joint and/or broken parts. Bevel cracks either by pneumatic chiseling or by grinding.
TECHNICAL DATA Typical Tensile Strength: 65,000 psi (450 N/mm2) Typical Hardness: 80 HRB Color Match Properties Deposits are brass-yellow Bonding Temperature: 1600° to 1650°F Preheating: 500° to 700°F
Note: When grinding make sure not to “color” the surface that indicates overheating and potential hard-spotting. Align parts and preheat within the recommended 500° to 700°F temperature-range. Technique: Rapidly sear the joint by using an excess oxygen flame. Apply a small amount of EutecTor 16D as a supplemental flux along the joint area and lightly “tin” the surfaces to be joined using a neutral flame. After tinning apply filler metal using a continuous “drop-and-melt” technique. Continue until the joint is slightly overfilled. Note: Any excess “glassy” flux residue can be readily removed by light scraping.
TYPICAL APPLICATIONS Although formulated for cast iron components such as cast iron brackets, end-flanges, malleable piping and agricultural implements, Xuper 146XFC is also recommended for car body repairs, light tubular constructions, and sheet metal fabrications.
Post-brazing: Allow the brazed casting to slow-cool either by covering in vermiculite, wrapping in a heat-retardant blanket, or by burying in lime.
