Applications / Features
High-performance electrode for
hardfacing sealing surfaces exposed to high pressure and
high temperatures.
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.
Applications
Suitable for wear-resistant hardfacing welds
on unalloyed, low-alloy and high-alloy heat-resistant, stainless and
acid-resistant steels and steel castings.
