Classifications nickel-based
EN ISO 14172: AWS A5.11:
E Ni 6625 (NiCr22Mo9Nb) ENiCrMo-3
Characteristics and field of use
Core wire alloyed special stick electrode with special basic coating for high quality welded joints of nickel-
based alloys with a high Mo content (. Alloy 625 and Alloy 825) and of CrNiMo steels with a high
Mo content (. 6% Mo steels). This type is also suitable for creep resistant and highly creep resistant
steels， heat resistant and cryogenic materials， dissimilar joints and low-alloy， hard-to-weld steels. Suitable
for pressure vessel construction for -196°C to +550°C， otherwise with scaling resistance up to +1200°C
(sulphur-free atmosphere). Because of the embrittlement of the base material between 600 and 850°C，
use in this temperature range should be avoided. High resistance to hot cracking， in addition to which the
C-diffusion at high emperatures or during heat treatment of dissimilar joints is largely inhibited. Extremely
high resistance to stress corrosion cracking and pitting (PREN 52). Resistant to thermal shock， stainless，
fully austenitic. Low expansion coefficient between C-steel and austenitic CrNi(Mo) steel. Exceptional welding
properties in all positions except for vertical down， good slag detachability， high resistance to porosity，
notch-free weld seams， high degree of purity. The electrode and the weld metal meet the highest quality
requirements.
