Characteristics and typical fields of application
GMAW for 2.25 % Cr 1 % Mo alloyed boiler, plate and tube steels as well as in oil refineries e.g. in
crack plants. Preferably used for the base metal 10CrMo9-10 (ASTM A335 Gr. P22) Approved in
long-term condition up to +600 °C service temperature. Also for similar alloyed quenched and
tempered steels and case hardening steels. The deposit is noted for its good mechanical properties
and cracking resistance, but also for its creep rupture strength which is within the scatter band of
10CrMo9-10.
The wire shows very good feeding characteristics, resulting in smooth welding and wetting
behaviour.
Base materials
Creep resistance steels and similar alloyed cast steels, QT-steels similar alloyed up to 980 MPa
tensile strength, similar alloyed case hardening steels, nitriding steels
