Ni-alloyed, basic coated stick electrode.
Stick electrode for welding of unalloyed and Ni-alloyed cryogenic fine grained steels.
FOX 2,5 Ni is alloyed with 2,5 % Ni, according to the name. The big benefit of this alloy is the very high ductility at low temperatures. Therefore, specific applications like in the offshore industry with its high requirements are mostly the focus for this electrode.
The very low hydrogen content and the moisture resistant coating is standard for our basic coated high strength stick electrodes.
These properties are perfectly supporting the usage of this electrode especially for applications in these industries, where difficult environmental conditions often are the case.
Typical Applications
- Steel construction under extreme conditions
- Offshore Industry
- Cryogenic ship building steels (e.g. icebreaker)
