- AUSTENITIC STAINLESS STEELS
312
Description
Solid rod for dissimilar joints and difficult to weld steels
These consumables are used to weld similar steels, medium and high carbon hardenable steels. The rod has extreme tolerance to dilution and is useful for welding 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. The weld deposit is work hardenable and provides good wear resistance. Applications include tool steels, shafts, gear teeth, free-cutting steels, dissimilar alloy combinations, buffer layers, and weld overlay.
