SMAW Electrodes
AMA 16Cr11
-
E 6–UM–55
DIN 8555 :
Application/properties:
basic-covered electrode is suitable for hard facing cutting edges, press dies, dredging pump parts and liners that are subject to wear at high temperatures. The weld metal has an austenitic structure that has relatively good wear resistance at high temperatures.
