Description
Solid rod Ni, 29% Cr, 9% Fe, 0,75%Nb for alloy 690
Designed to match alloy 690, often used in place of alloy 600 for high temperature corrosion applications. This product is enriched with Boron and Zirconium to minimize the tendency for ductility-dip cracking and oxide inclusions. It's especially used in the nuclear industry where the higher Chromium content provides greater resistance to stress-corrosion cracking in the nuclear water environment. This product is also suitable to overlay carbon and low alloy steels and can be used in applications requiring resistance to oxidizing acids.
