G-TECH 840B
SMAW
- DISSIMILAR STEELS
Description
High recovery basic Ni-based covered electrode
Suitable for
joining and cladding low alloyed and alloyed steels, welding iron- and
nickel base alloys and for dissimilar joints. The austenitic deposit is insensitive to hot-cracking and free of embrittlement at high as well as at low temperatures, non-scaling up to 1000° C, and cold tough down to 196° C. No diffusion of carbon into the weld metal at high temperatures. Used for service-temperatures of more than 300° C in chemical and petrochemical industry, glassworks, civil engineering, repairing and maintenance workshops.
