Stainless electrode for repairing and surfacing
Description & applications
Rutile-basic electrode with high recovery (160%). Fully austenitic stainless steel deposit with a high Mn-content. For welding and cladding on Mn-steels (14% Mn), for dissimilar joints and difficult to weld materials, cushion layers prior hardfacing, repairing of pieces submitted to shocks.
Easy to use, soft fusion, low spatters, slag easy to remove, regular weld beads, deposit highly resistant to cracks.
Main applications: For shops doing repairs on railways, earth moving, in quarries or on construction machinery, in cement works, on different types of crushers.
