[0029) A porcelain coated steel wire oven rack. The preferred coated steel wire oven rack includes a plurality of elongated steel wire members joined together to form an oven rack having an outer surface. The plurality of elongated steel wire members are made fro m a steel rod material containing from about 80 to about 99.9% by weight of iron, from abo ut 0.001 to about 0.08% by weight of carbon and from about 0.001 to about 0.2% by weight of a carbon stabilizing transition metal, preferably selected from the group consisting of Vanadium, Tantalum, Titanium and Niobium. The plurality of elongated steel wire member s are preferably made from the steel rod material by drawing the steel rod material to form steel wire; wherein the diameter of the cross-sectional area of the steel rod material is reduce d by at least about 20% when the steel rod material is drawn to form the steel wire to prevent chipping of the glass material from the outer surface due to the release of hydrogen gas from the steel wire members when the steel wire is heated above 900.degree.F. |
