GTAW
- DISSIMILAR STEELS
Description
Rod depositing high Cr-Ni alloy.
This rod is used to weld similar steels, medium and high carbon hardenable steels. The weld metal has extreme tolerance to dilution and it is useful to weld unknown specification steels. Even with considerable dilution by austenite-forming elements such as nickel, the microstructure remains two-phase A/F and thus highly resistant to weld metal cracks and fissures. Weld deposit is work hardenable and gives good wear resistance. Applications include tool steels, shafts, gear teeth, free-cutting steels, dissimilar alloy combinations, buffer layers, weld overlay.
