F Cr-Mo 91

AWS: SFA 5.28 ER90S-B9

EN ISO CODE: 21952-B-W I1 9C1MV

F Cr-Mo 91 is copper-coated a solid wire for GTAW, yielding 9%Cr - 1%Mo and modified with Niobium, Vanadium and Nitrogen designed to provide improved creep strength, toughness, fatigue life, oxidation and corrosion resistance at elevated temperatures. The wire gives stable arc, smooth welding performance and deposits radiographic quality welds. F Cr-Mo 91 designed to weld the materials in power plant, refineries, naptha cracker units, etc. Following are some of the steels that can be welded with this wire.

I) Plate: A 387 Gr.91 (II) Pipes: A 335-P91 (III) Tubes: A 213 - T91
