Description: AFM E9018-B9 is a 9% Cr-1% Mo, low hydrogen electrode modified with niobium (columbium) and vanadium designed to provide improved creep strength, toughness, fatigue life, and oxidation and corrosion resistance at elevated temperatures. It is similar to AFM E9015-B9, except it contains an addition of iron powder which improves deposition rates. Due to the higher elevated temperature properties of AFM E9018-B9, components that are now fabricated from stainless and ferritic steels may be fabricated from a single alloy, eliminating the problems associated with dissimilar welds.
Applications: AFM E9018-B9 is used for welding A213-T91 Tube, A335-P91 Pipe, and A387 Gr. 91 Plate.
