ENiCrMo–6
AWS/ASME SFA – 5.11:Application/properties:
Basic electrode for welding of Ni-base alloys. This electrode is specially used for welding of 5% Ni and 9% Ni steels for low temperature operation. The electrode can be welded with AC current to avoid the arc below. It is recommended to use arc length as short as possible.
