Nicrofer 5219 Nb - alloy 718
MATERIAL DESCRIPTION, MAIN CHARACTERISTICS
The alloy 718 is a niobium and molybdenum - containing nickel-iron-chromium alloy, age-hardenable through aluminium and titanium additions.
It has an excellent corrosion resistance at high and low temperatures, good resistance to pitting and stress corrosion cracking.
This alloy, the Nicrofer 5219 Nb, has good mechanical propereties: high fatigue strength and creep rupture strength up to 700°C (1300°F) and resistance to oxidation up to 1000°C (1840°F). Solution-annealed, age-hardened.
Weldability: annealed -> satisfactory
