Alloy 91T1-B3 is a low alloy steel electrode for single and multiple pass welding of 2.25% chromium, 1 % molybdenum high temperature creep resistant steels in all positions. The fast freezing slag system provides high welder appeal and easy removal. This alloy is formulated for welding ASTM A387 Gr. 22 plate and A335 P22 pipe steels. Extensively used in the fabrication of pressure vessels, boilers, heat exchangers and other applications involved with high temperature exposure and creep resistance. Shielding Gas: 100% CO2 @ 35-50 cfh Information provided by Universal Wire Works for their line of welding wire and filler metal. |
