Description: AFM 112 is designed for welding alloy 625 to itself and for joining many dissimilar nickel baring alloys and iron-base metals. AFM 112 is also recommended for welding nickel base alloys 600 and 601 and nickel-iron-chrome alloys 800 and 801. It also can be used for joining nickel based alloys 625, 718, X750 and 706 to 9% nickel steel and for overlaying carbon steel.
