- CRYOGENIC STEELS
2Ni
Description
Basic coated electrode with 2,5% Ni
Electrode designed for welding low-alloy fine grain steels and nickel
steels with impact requirements down to -75°C. Suitable for the
construction of cryogenic plant and pipework in petrochemical industry
and for general low temperature applications. Its basic coating ensures excellent positional welding characteristics with good gap bridging ability. The weld pool and slag are easy to control and facilitate the achievement of a clean bead surface even in narrow preparations and in root pass.
