Abstract:
A steel alloy which is particularly suitable for use in manufacturing reinforcing wire for rubber products consists of (a) iron, (b) about 1.05 to about 1.7 weight percent carbon, (c) about 0.2 to about 0.8 weight percent manganese, (d) about 0.1 to about 0.8 weight percent silicon, (e) about 0.1 to about 0.7 weight percent chromium and (f) about 0.02 to about 0.3 weight percent copper (g) 0.0 to about 0.5 weight percent nickel, (h) 0.0 to about 0.5 weight percent molybdenum and (i) 0.0 to about 0.5 weight percent vanadium; with the proviso that the carbon equivalent of the steel alloy is within the range of 1.15 to 1.8 weight percent, wherein the carbon equivalent is determined by the equation: ##EQU4## wherein CE represents the carbon equivalent, wherein C represents the weight percentage of carbon in the steel alloy, wherein Mn represents the weight percentage of manganese in the steel alloy, wherein Si represents the weight percentage of silicon in the steel alloy, wherein Ni represents the weight percentage of nickel in the steel alloy, wherein Cu represents the weight percentage of copper in the steel alloy, wherein Cr represents the weight percentage of chromium in the steel alloy, wherein Mo represents the weight percentage of molybdenum in the steel alloy and wherein V represents the weight percentage of vanadium in the steel alloy.
