To achieve a drawn wire with a tensile strength defined by the equation of Y=Yo
exp(A2d) wherein Y is the tensile strength in MPa
(N/mm2), Yo is the strength of as patented wire, A2
is a coefficient dependant on wire chemistry and drawing conditions, and
d is a total true drawing strain, a high carbon steel wire contains
0.95 to 1.3% carbon and a combination of chromium, manganese, silicon, cobalt,
niobium, and boron is processed such that the bright wire of an intermediate diameter
has a structure void of micro cracks, patented to produce a desired microstructure
with defined inter-lamella spacing and austenite grain, coated with brass, and
fine drawn with an optimized die draft schedule at a specified true strain.
