E12018-M
AWS A5.5 E12018-M
ASME SFA 5.5 E12018-M
12018M is an all-position, low-hydrogen iron powder electrode containing manganese, chromium, nickel and molybdenum. 12018M was developed for welding high strength steels requiring a weld deposit tensile strength of 120,000 psi minimum. The weld deposits of 12018M have excellent impact properties and are X-ray quality. 12018M is designed for welding high tensile strength steels such as ASTM A148 Gr. 120-95, A238 Gr.F, A291 class 4, A514 and many other specifications all requiring a weld deposit tensile strength of 120,000 psi minimum.
