Can cast iron be hard-faced?

Yes, but you must take preheat and inter-pass temperatures into account. Nickel and nickel-iron products usually are suitable for rebuilding cast iron. These products aren’t affected by the carbon content of the parent metal and remain ductile. Multiple layers are possible. If further wear protection is required, metal carbide products can work well on top of the nickel or nickel-iron buildup.

These frequently asked questions only begin to address hard-facing. Hard-facing product manufacturers and specialists can contribute to a greater in-depth understanding of hard-facing and help assist you in product and process selection for your application
