Wire on the other 14-131-983-2001 supplied in cold-worked condition with the calculated degree of cold deformation of 30-50%. Check the wire on the winding. After winding five turns of wire on a rod with a diameter equal to four times the diameter of the wire, it should not have cracks and delamination. |
