Characteristics and typical fields of application
Rutile electrode of type E 23 12 L / 309L providing increased delta ferrite contents (FN ~17) in the
weld deposit for safe and crack resistant dissimilar joint welds and surfacing.
BÖHLER AWS E309L-17 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 -60°C to +300°C and for weld claddings up to +400°C.
Base materials
Joints of and between high-strength, unalloyed and alloyed quenched and tempered steels,
stainless, ferritic Cr and austenitic Cr-Ni steels, austenitic manganese steels and weld claddings:
for the first layer of chemically resistant weld claddings on the ferritic-pearlitic steels used for boiler
and pressure vessel construction up to fine-grained structural steel S500N, and for the creep
resistant fine-grained structural steels 22NiMoCr4-7, 20MnMoNi5-5 and GS-18NiMoCr 3 7
