Description: AFM ER410NiMo is primarily designed for welding ASTM CA6NM castings or similar
material, as well as light gage 410, 410S, and 405 base metals. AFM ER410NiMo
is modified to contain less chromium and more nickel to eliminate ferrite in the
microstructure as it has a deleterious effect on mechanical properties. Final
postweld heat treatment should not exceed 1150¡ÆF (620¡ÆC), as higher temperatures
may result in rehardening due to untempered martensite in the microstructure
after cooling to room temperature.
