Description
Non- synthetic electrode depositing Ni-Cr-Fe weld metal, which is very good resistance to SCC and IGC due to low carbon content and absence of sigma phase. Control boron and zirconium are helpful in reducing the tendency for ductility dip cracking. It has scaling o temperature up to 1100 C in air. It is ideally suited for welding the Ni-Cr-Fe alloy of the UNS number N06690. It is also use for the welding of Ni-Cr-Fe alloys to steels and stainless steels, and for corrosion resistant overlays on steels. Typical specifications for Ni-Cr-Fe base metals are ASTM B166, B167 and B168. Ideal for stringent requirements in the construction of nuclear reactors
