Wire rope, nominal diamater 2". The wire includes an independent core (IWRC) with 7 wires of 2.0 mm and 6 strands with 26 wires (1+5+[5+5]+10). The external strand layer presents a 3.8mm wire, and there are two internal strand layers with different wire sizes. The wire rope presents plastic reinforcement. It is a right regular lay AACI made by extra improved plow steel (EIPS) wires.

Cm - Nital Etched Micrography by OMDf - Base Metal
Macrography of a longitudinal section of a 4 mm diameter wire, presenting part of an austogenously welded joint, with the transformation of the strain hardened pearlitic. The base metal is to the left side of the figure, and the heat affected zone is in the center of the figure. There is a (previous austenite) grain growth to the right side of the figure, where it is the center of the weld.
