Flux-cored wire provides low-temperature toughness for critical applications

FabCO® 812-Ni1M wire from Hobart has been formulated to provide low-temperature impact toughness for critical applications, including offshore drilling rigs, transmission and process piping, jackup rig fabrication, and shipbuilding. Low diffusible hydrogen levels and low moisture pickup help mitigate the risk of cracking, even after wire exposure, and can reduce preheat requirements to minimize downtime for weld preparation, the company states.

This gas-shielded, low-alloy wire consistently maintains good mechanical properties in the as-welded condition and after postweld stress relief. It creates a weld deposit containing less than 1 percent nickel and less than 248 HV10 hardness.

Mo2, the wire creates welds with a tensile strength of 93,000 PSI and a yield strength of 80,000 PSI. The wire is usable for all-position welding for single- or multipass applications.
