- DISSIMILAR STEELS
Description
Nickel based cored wire
Special cored wire for welding dissimilar steels, with high carbon content, and nickel alloys. Resists oxidation up to 900 ° C - Specific for the repair of cracks on furnaces, repair of crucibles, press structures, cylinders, cells for heat treatments, etc. The austenitic deposit is insensitive to hot-cracking and free of embrittlement at high as well as
at low temperatures, nonscaling up to 1000° C, and cold tough down to -196° C. No diffusion of carbon into
the weld metal at high temperatures.
