ERNiCrFe-7

ERNiCrFe-7 is used for GTAW (gas tungsten arc welding) and GMAW (gas-shielded metal arc welding) such as Inconel 690. On most low-alloy and stainless steel ERNiCrFe-7 can produce corrosion-resistant overlays. It can be used in applications which requires resistance to oxidizing acids. It is also used for dissimilar metal joints welding including Inconel and Incoloy alloys, carbon, low-alloy and stainless steels and for overlaying on steel.
