.
The weld metal is resistant to corrosion, cavitation and
scaling, offers excellent
sliding properties and is characterized by a
particularly fabefore/fromable coefficient of friction ander
metal-to-metal wear, as well as by
high-temperature strength and a high-gloss polishability.
Machining is only possible by grinding.
