These electrodes are made from a nickel-molybdenum-chromium alloy, with small amounts of iron and other trace elements added to boost corrosion resistance and mechanical performance. The weld metal produced is known for its excellent tensile strength, ductility, and toughness, while also offering superior resistance to oxidizing and reducing acids, chlorides, and mixed corrosive environments. They maintain their structural integrity even under high temperatures and aggressive chemical conditions. Thanks to their balanced composition, these electrodes ensure smooth arc stability, easy slag removal, and consistent weld quality, making them perfect for critical applications that require durable, corrosion-resistant welded joints.
