Application
Type #1 Flux Cored Wire (ERCCoCr-C) is a tubular wire version of the highest hardness standard cobalt alloy used with chromium carbides that impact outstanding abrasive wear resistance. The addition of tungsten enhances high temperature hardness and matrix toughness for excellent adhesive and solid particle erosion wear resistance. It bonds well with all weldable steels including stainless.
