What is AWS Class E8018-B8 Coated Electrodes?
AWS Class E8018-B8 coated electrodes are low-hydrogen, iron powder electrodes primarily designed for welding 9Cr-1Mo alloy steels used in high-temperature and pressure applications. Their typical chemical composition includes Chromium (8–10%), Molybdenum (0.9–1.2%), Carbon (≤0.12%), Manganese (0.3–0.6%), and Silicon (≤0.9%), ensuring high-temperature strength and corrosion resistance. Mechanical properties feature tensile strength of 550–690 MPa, yield strength of 450 MPa (minimum), elongation of 20% (minimum), and excellent impact toughness. These electrodes provide outstanding creep resistance, crack resistance, and weld integrity in demanding service conditions.
