Description
Rutile electrode of type E 23 12 2 L / 309MoL providing increased delta ferrite contents
(FN ~20) in the weld deposit for safe and crack resistant dissimilar joint welds as well as
surfacing or root passes of clad steel. BÖHLER FOX CN 23/12 Mo-A is noted for its superior
welding characteristics and metallurgy. It can be used on AC and DC. Other advantages
include high current carrying capacity, minimum spatter formation, self releasing slag, smooth
and clean weld profile, safety against formation of porosity due to the moisture resistant
coating and its packaging into hermetically sealed tins.
Operating temperature from -10 °C to +300 °C and for weld surfacing (1st layer) up to +400 °C.
Approvals and Certificates
TÜV-D (1362.), TÜV-A (34), ABS (E 309 Mo), RINA (309Mo), DNV (309MoL), LR (DXV u. 0,
CMnSS), BV (309 Mo), LTSS, VUZ, SEPROZ, CE, NAKS
Base Materials
dissimilar joint welds:
mild steels and low-alloyed constructional and QT-steels among themselves or among each
other; unalloyed as well as low-alloyed boiler or constructional steels with stainless Cr-, CrNiand
CrNiMo-steels; ferritic-austenitic joint welds in boiler and pressure vessel parts.
weld surfacing: for the first layer of corrosion resistant surfacing on P235GH, P265GH, S255N,
P295GH, S355N - S500N; for the first layer of corrosion resistant weld surfacing on high temperature
quenched and tempered fine-grained steels acc. AD-Merkblatt HPO, class 3.
