# 1 Coated is the highest hardness standard cobalt alloy in the group of cobalt alloys used for elevated temperature abrasive wear associated with corrosion. Deposits of this alloy have a large volume of chromium carbides that impart 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 steels including stainless.

# 1-M is the tubular wire version of the highest hardness standard cobalt alloy used with chromium carbides that impart 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. Typical applications include screw components, cross heads, hydropulper disc segments, soaking pit-tong bits, mixer rotors, bodies and tip sides, pump sleeves and valves & pumps

# 21 Bare rod deposits a low carbon austenitic cobalt type alloy with excellent work hardenability, high temperature, strength, and impact resistance. These deposits are quite stable during thermal cycling, making them a favorite for hot die materials. They have good strength and ductility in temperatures up to 2100? F. Resistance to galling (self-mated) corrosion and cavitation erosion make # 21 Bare is a good choice for valve trim on steam and fluid control valve bodies and seats. It bonds well to all weldable steels, including stainless.
