Description and applications*
* Illustrative, not-exhaustive list
Age hardenable nickel-chromium alloy that combines high corrosion resistance and high mechanical properties with good behaviour during forming.
This filler metal shows outstanding resistance to a wide range of highly corrosive media and high creep-rupture at temperatures ranging from -250°C to 700°C.
The weld metal will age harden on heat treatment, then being characterized by high strength and outstanding resistance to postweld cracking due to Ti, Al and Nb addition.
Used in a wide range of applications, such as:
• welding of nickel base alloys such as 718, 750 or 706 grades by every automatic welding methods (GMAW, GTAW, etc.);
• components for liquid fuelled rockets;
• rings, casings, and various formed metal parts for gas turbine engines;
• cryogenic tanks;
• applications in petrochemical, automotive, aircraft industries.
