Characteristics and application
TIG/GTAW rod for welding of high strength steels, used predominantly after stress relieving. Predominantly used for welding high strength steels, providing a good combination of strength and toughness. May find use for joining creep resistance steels up to ~500°C but the WSG Mo wire would be the more usual choice.
Base materials
For a wide range of engineering steels with a yield strength up to 540MPa (78ksi) and UTS up to 620MPa (90ksi).
