Classifications high-alloyed
EN ISO 3581-A: AWS A5.4:
E Z18 9 MnMo R 3 2 E307-16 (mod.)
Characteristics and field of use
Core wire alloyed electrode with rutile-basic coating for joints between dissimilar steels, steels that
are hard to weld and 14% Mn steels. Well suited for tough intermediate layers in case of hardfacing.
Properties of the weld bl: suitable for strain-hardening, very good cavitation resistance, crack
resistant, resistant to thermal shock, resistant to scaling up to +850°C, little tendency to sigma-phase
embrittlement above 500°C. Heat treatment is possible. Consultation with the manufacturer is recommended
for operating temperatures above +650°C. Exceptional toughness of the weld bl even
at high dilution levels with hard-to-weld steels or when subject to thermal shock. Cryogenic down to
-100°C. Stable arc even with AC power.
Base materials
high-strength, unalloyed and alloyed structural, quenched and tempered and armour steels among
themselves or among each other; unalloyed and alloyed boiler or structural steels with high-alloyed
Cr and Cr-Ni steels; heat-resistant steels up to +850°C; austenitic manganese steels together and
with other steels; cryogenic plate and pipe steels together with cryogenic austenitic materials.
