~ E
NiCrMo-3
Application / Properties:
Basic-covered electrode with
63% Ni and 22% Cr and 9%Mo
for the welding of:
-Highly corrosion resistant
nickel-chromium-molybdenum-alloys,
e.g.:NiCr22Mo9Nb(2.4856),NiCr21Mo(2.4858),NiCr22Mo6Cu(2.4618).
-austenitic steels of
highest corrosion
resistance,
e.g:1.4529(x1NiCrMoCuN25206),1.4547(X1CrNiMoCuN20-18-7)
-cryogenic nickel-alloyed
steels,e.g.:X8Ni9(1.5662)
