The **AWS Class ENiCrMo-3 Coated Electrodes** are made up of about 65–70% Nickel, 20–25% Chromium, 5–10% Molybdenum, along with trace amounts of Iron, Manganese, and Silicon. This unique blend gives them exceptional resistance to both oxidizing and reducing acids, as well as pitting and crevice corrosion, not to mention high-temperature oxidation. With a tensile strength of around 690 MPa, yield strength of 480 MPa, and an elongation of up to 35%, these electrodes ensure that welds are not only strong but also ductile and reliable. They boast stable arc performance, minimal spatter, and easy slag removal, resulting in clean, metallurgically sound weld deposits.
