AWS A5.1 E9018-M
ASME SFA 5.1 E9018-M
9018M is an all-position, low-hydrogen, iron-powder electrode containing manganese, molybdenum and nickel. 9018M is designed for welding low alloy, high tensile, quenched and tempered steels such as T1, HY80 and HY90. Weld deposits have excellent impact properties and are X-ray quality. PREHEATING AND POSTHEATING Depending upon the thickness and hardening characteristics of the work piece, preheating at a temperature between 140-220° F is recommended.
TYPICAL APPLICATIONS 9018M is commonly used to make attachment welds on steels in the 90.000 psi tensile strength range. Typical applications would involve pressure vessels, bridges, machinery and penstocks. Base metals would include ASTM A225 Gr. B, A235 Gr. G, A288 class 2, A291 class 1, 2 and many others.
