Description
ERNiCr-4 is a high Chromium-Nickel alloy used for joining, re-pair and overlay cladding of Ni-Cr and Ni-Fe-Cr components. It re-sists high temperature corrosion including fuel-ash corrosion and erosion in atmospheres containing sulfur. It can equivalent to:  FM72M  Techalloy 72.
Applications
High Chromium Nickel alloy used for joining, repair and overlay cladding of Ni-Cr and Ni-Fe-Cr components. Material is resistant to high temperature corrosion including fuel-ash corrosion and erosion in atmospheres containing sulpher. This material is primarily used for boiler tube overlay in coal fired boiler systems.
