Abstract
This invention reveals steel alloys which are particularly suitable for use in manufacturing reinforcing wires for rubber products, such as tires. The steel filaments made by this process have an outstanding combination of strength and ductility. Additionally, the steel alloys of this invention can be patented in a low cost process due to their having a very fast rate of isothermal transformation. This allows the steel in the steel wire being patented to transform from a face centered cubic microstructure to an essentially body centered cubic microstructure within a very short period. This invention more specifically discloses a steel alloy composition which is particularly suitable for use in manufacturing reinforcing wire for rubber products which consists essentially of (a) about 92.8 to about 99.18 weight percent iron, (b) about 0.4 to about 1.5 weight percent carbon, (c) about 0.05 to about 1 weight percent silicon, (d) about 0.05 to about 1.2 weight percent manganese, (e) about 0.01 to about 1.4 weight percent chromium, (f) about 0.3 to about 1.6 weight percent cobalt, and (g) from about 0.01 to about 0.5 weight percent nickel.
