- AUSTENITIC STAINLESS STEELS
312
Description
Rod for dissimilar joints and hard-to-weld steels
This rod is used for the welding of steels with similar composition and for medium and high carbon hardenable steels. It is characterized by a considerable dilution tolerance and proves useful for welding steels of unknown composition. Even with significant dilution, thanks to austenitizing elements like nickel, the microstructure of the deposit remains biphasic and thus highly resistant to cracks and fissures. The deposit may be subject to work hardening and offers good wear resistance. Applications include tool steels, shafts, gear teeth, free machining steels, dissimilar welds, bearing and overlay layers.
