B?HLER FOX NIBAS 70/20 Stick electrode
Classifications nickel-based
EN ISO 14172: AWS A5.11:
E Ni 6082 (NiCr20Mn3Nb) ENiCrFe-3 (mod.)
Characteristics and field of use
Core wire alloyed special stick electrode corresponding to AWS ENiCrFe-3 with special basic coating，
for high-quality welding of nickel-based alloys， creep resistant and highly creep resistant steels， heat-
resistant and cryogenic materials， and also for low-alloy hard-to-weld steels and dissimilar joints.
Also for ferrite-austenite joints at operating temperatures ≥ 300°C or heat for
pressure vessel construction for -196 °C to +650°C， otherwise with scaling resistance up to +1200°C
(sulphur-free atmosphere). Does not tend to embrittlement， high resistance to hot cracking， in addition
to which the C-diffusion at high temperatures or during heat treatment of dissimilar joints is largely
inhibited. Resistant to thermal shock， stainless， fully austenitic. Low expansion coefficient between
C-steel and austenitic Cr-Ni-(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.
Base materials
2.4816 NiCr15Fe， 2.4817 LC-NiCr15Fe Nickel and nickel alloys， low-temperature steels up to
X8Ni9， high-alloyed Cr and CrNiMo steels， particularly for dissimilar joints， and their joints to unalloyed，
low-alloy， creep resistant and highly creep resistant steels. Also suitable for Alloy 800.
