AWS E9015-B9 electrodes are low-hydrogen chromium-molybdenum alloy steel consumables, typically featuring around 9% chromium and 1% molybdenum. This specific alloy mix grants them high tensile strength, excellent creep resistance, and remarkable oxidation resistance at elevated temperatures. The weld metal produced boasts a minimum tensile strength of about 620 MPa, along with good ductility and stable mechanical properties after post-weld heat treatment. These electrodes maintain low hydrogen levels and offer strong resistance to hydrogen-induced cracking.
