The improved slag system of this wire provides the superior welder appeal of acid slag (-T1) products and the mechanical properties normally associated with basic slag wires. Weld metal diffusible hydrogen levels are kept low, making this an excellent choice for the more demanding applications. The wire can be used with either 100% CO² or a 75% Ar/25% CO² gas mixture for shielding.
The FabCO 811N1 is designed for mining and earthmoving equipment and other fabrication where low temperature impact values are needed. It is recommended for weathering-steel fabrication where colour match is not required.
