AWS Class ENiCrFe-3 coated electrodes are designed for welding nickel-chromium-iron alloys, offering excellent corrosion resistance and high-temperature performance. Their typical chemical composition includes 45–65% nickel (Ni), 20–25% chromium (Cr), 4–7% iron (Fe), with small amounts of manganese, silicon, and carbon. Mechanically, weld deposits exhibit high tensile strength (around 70–90 ksi), good elongation (25–35%), and exceptional toughness, maintaining strength at elevated temperatures. These electrodes produce smooth, slag-free welds with minimal spatter, making them ideal for chemical, petrochemical, and high-temperature applications requiring durability, oxidation resistance, and structural reliability.
