These electrodes have 23–25% chromium, 12–14% nickel, and 2–3% molybdenum. Carbon is restricted to ≤0.04% for greater corrosion resistance. They have tensile strength over 570 MPa with elongation of approximately 30%. They maintain excellent toughness at low and elevated temperatures. They work efficiently with AC or DC current to form a stable arc and smooth, clean welds. The presence of molybdenum increases resistance to localized corrosion in acidic or brine surroundings, which makes them well suited to high-service environments.
