The high content of hard hypereutectic phases M7C3 makes the alloy suitable for high abrasive wear using CORODUR® 56, a flux cored wire electrode, which is highly C- and Cr- alloyed. The weld deposit has a high corrosion resistance. Best results are achieved by welding in 2-3 layers with max. 10 mm thickness. The deposit should be subjected to little impact stress. Before cladding sensitive base materials and overlaying old, previously hard-faced surfaces, a ductile buffering layer of CORODUR® 200 K or 250 K is recommended.
