Description
Nickel rod, 29% Cr, 9% Fe, 0.75% Nb for alloy 690
Designed for welding alloy 690, this rod is an alternative to alloy 600 in applications subjected to high-temperature corrosion. The formulation is enriched with boron and zirconium, elements that help significantly reduce liquation cracking and oxide inclusions. It is particularly suitable for use in the nuclear industry, where the high chromium content provides superior resistance to stress corrosion in high-temperature aqueous environments. Also suitable for cladding operations on carbon and alloy steels, as well as for applications requiring high resistance to oxidizing agents.
