Ni-Cr-Fe Filler Metal

INCONEL Filler Metal 52 is used for gas-tungsten-arc and gas-metal-arc welding of INCONEL alloy 690. This NiCrFe welding product was developed to meet the changing needs of the nuclear industry, the higher chromium level providing greater resistance to stress-corrosion cracking in the nuclear, pure water environment. INCONEL Filler Metal 52 produces corrosion-resistant overlays on most low-alloy and stainless steels. It can also be used in applications requiring resistance to oxidizing acids. It is useful for dissimilar joints involving INCONEL and INCOLOY alloys, and carbon, low-alloy and stainless steels and for overlaying on to steel.
