Applications / Features
stick electrode for sealing surface overlays,
which are subject to high compression and elevated temperatures
.
The weld metal is corrosion-, cavitation- and
scale-resistant, has excellent
sliding properties and is characterised by a
particularly favourable coefficient of friction ander
metal-on-metal wear and by
heat resistance and high-gloss polishability.
Machining is possible by grinding only.
Applications
Suitable for wear-resistant hardfacing welds
on unalloyed, low-alloy and high-alloy heat-resistant, stainless and
acid-resistant steels and steel castings.
