Description: AFM E91T1-B3 is an all-position flux cored wire that contains 2-1/4% Cr-1% Mo. The weld metal analysis is similar to AFM E9018-B3 low hydrogen electrode. It is recommended for welding 2-1/4% Cr-1% Mo steels, such as ASTM A335-P22 pipe and ASTM A387 Gr.22 plate, and can be used for single or multiple pass welding. AFM E91T1-B3 can be used with 100% CO2 or Argon mixtures up to 75% Argon.
