UltraCore® 712A80 is Lincoln's best running E71T-12 product because of its superior arc characteristics and high impacts in a variety of applications, including offshore, tank and pressure vessel fabrication. Robust impact toughness values — even with a notch offset of 2.5 mm from weld centerline — makes this a favorite for designers who need consistently high impacts weld after weld. Tensiles will not exceed 90 ksi to help reduce cracking tendency, and the new ProTech™ foil bag packaging system protects the wire from harmful moisture contamination
