Stellite 6 equivalent – POLYSTEL 6

Metal Cored POLYSTEL 6 is a cobalt-based metal cored wire. It is widely considered the principal cobalt alloy in terms of versatility and resistance to many forms of mechanical and chemical deterioration over an extensive temperature range. POLYSTEL 6 attributes its outstanding self-mated anti-galling properties to the high alloy content of the matrix, namely the chromium carbides contained in the deposit. Popular applications for this alloy include hardfacing applications when wear is complimented by corrosion and/or elevated temperatures such as valve seats and bearing areas. This alloy an be applied to any weldable steel, including all grades of stainless steel.

Solid POLYSTEL 6 is designed for high temperature applications. POLYSTEL 6 provides excellent wear resistance in abrasion as well as in metal to metal applications. Wear resistance is provided by the complex chromium and tungsten carbides that are supported in a rich cobalt matrix. POLYSTEL 6 is also resistant to oxidation up to its melting range and can be satisfactorily specified in sour gas as well as other corrosive applications.
