...Abstract Abstract Extra high strength zinc-coated 1080 steel welded wire was wound into seven-wire cable strands for use in aerial cables and guy wires. The wires and cable strands failed tensile, elongation, and wrap tests, with wires fracturing near welds at 2.5 to 3.5% elongation and through...

.... The hammerhead material was UNS G10800 (AISI/SAE grade 1080). Excessive hardnesses were measured in the first 3 mm (0. 12 in.) below the striking surface, indicating that there was lack of control during the final tempering operation.

... particles could be either copper or a copper alloy as shown by the optical and SEM microphotographs. The diffusion of copper (melting point 1080 °C) in to the grain steel boundaries was the reason for the cracks on the bend extrados surface. Copper diffusion weakens the austenite grain boundary at ~980 °C...
