GTAW
- DISSIMILAR STEELS
Description
High Cr-Ni content rod.
Rod suitable for welding similar steels and hardenable steels with medium and high carbon content.
The filler metal exhibits a high tolerance to dilution, making it particularly suitable for welding steels with unknown composition.
Even with significant dilution from austenitizing elements like nickel, the deposit microstructure remains bi-phase A/F (austenite/ferrite), ensuring excellent resistance to cracks and fissures.
The deposited material is non-hardenable and provides good wear resistance.
Typical applications include welding of tool steels, shafts, gear teeth, automatic steels, joints between different alloys, buffer layers, and protective overlays.
