Description
Co 1, is a cobalt based bare rod that has the highest hardness and wear resistance of the standard cobalt alloys. Co 1 is used in elevated temperature, high wear applications. It is difficult to machine requiring carbide tools or grinding. It can be applied to all weldable steels, including stainless steels. It equivalent to: Stellite 1, Polystel 1.
Applications
Hydro pulper disc;
Oil drilling tools;
Mixer seals and rotors.
