To stop breakages during stranding high carbon steel wires:

1.- Do not over stress the wire during drawing, try to use a small total reduction of area to allow the wire to be able to stand further work during stranding. Meet tensile by carbon content.Check torsion to meet specifications.

2.- Check the patenting in order to obtain full austenization of the wire and right structure by correct time and temperature on the austenization furnace and the cooling furnace.

3.- Check the design of the cable to be sure it has the right lay

4.- Check strander to be sure all guides are in good shape.

For patentig structures can be seen in the wire Handbook of WAI in the patenting section.
