Low alloy TIG Welding Wire
Application/properties:
GTAW rod for Cr-Mo low alloyed boiler, plate and tube steels as well as in oil refineries. Preferably used for the base metal 10CrMo910 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.
