Description
ERNiCrFe-7 was developed to meet the changing needs of the nuchear industry, the higher chromium level providing greater resistance to stress-corrosion cracking in the nuclear, pure water environment.
Applications
ERNiCrFe-7 is used for welding high chromium-nickel based alloys such as Inconel 690. ERNiCrFe-7 also can be used for producing corrosion-resistant overlays on low- alloy and stainless steels and for dissimilar. ERNiCrFe-7 can be used in applications requiring resistance to oxidizing acids.
