Description: AFM E81T1-B2 is an all-position flux cored wire that contains 1-1/4% Cr-1/2% Mo. The weld metal analysis is very similar to AFM E8018-B2 low hydrogen electrode. It is used for welding 1/2% Cr-1/2% Mo, 1% Cr-1/2% Mo, and 1-1/4% Cr-1/2% Mo steels, such as ASTM A335-P11 pipe and ASTM A387 Gr.11 plate. The wire can be used in either single or multiple pass welding. AFM E81T1-B2 can be used with 100% CO2 or Argon mixtures up to 75% Argon.
