Strong 90S-B91
STRONG 90S-B91
Copper Coated Solid Wire For MIG & TIG Welding
STRONG 90S-B91 is copper-coated solid welding wire composing 9%Cr – 1%Mo and added
with Niobium, Vanadium & Nitrogen. This wire is specifically designed to provide improved
toughness and creep strength, weld fatigue life, oxidation & corrosion resistance at very high
temperatures.
STRONG 90S-B91 gives stable arc, smooth welding performance and deposits radiographic
quality welds. This wire is designed to weld materials in power plant, refineries, naphtha
cracker units, etc. Typical application in steel types like I) Plate: A 387 Gr.91 (II) Pipes: A 335-
P91 (III) Tubes: A 213 – T91.
