GTAW rod for welding of nickel-base alloys, high-temperature and creep resisting steels, heat resisting and cryogenic materials, low-alloyed problem steels and dissimilar joints. Ferritic austenitic joints is for service temperatures above +300°C or for applications where a post weld heat treatment is required . Suitable for pressure vessel fabrication for the service temperature range -196°C to +550°C, otherwise resistant to scaling up to +1200°C. Not susceptible to embrittlement. Resistant to thermal shocks, corrosion resistant, fully austenitic. Low coefficient of thermal expansion.
