ENiCrFe-3 Welding Electrode

1. Description

ENiCrFe-3 is a low-hydrogen type Ni70Cr15 heat-resistant alloy electrode. Since the weld metal contains a certain amount of Mn and Nb alloy elements, the weld has good crack resistance. AC and DC, with good welding process performance, good operability, good all-position weldability.

2. Application

ENiCrFe-3 welding electrode is used for welding nickel-based alloys for heat and corrosion resistance. It can also be used for welding and surfacing of hard-to-weld alloys and dissimilar steels.
