Abstract

A method of producing a steel product in the form of any one of wire, rod, and bar and products made from any one of wire, rod, and bar includes heat treating a mechanically worked steel product at a temperature below 1000ºC and for a time less than 16 hours and increasing the ductility and the yield stress of the steel. The increase in ductility, measured as elongation, of the heat treated steel relative to that of the mechanically worked steel is greater than 5%. The increase in the yield stress of the heat treated steel relative to that of the mechanically worked steel is greater than 5%. The invention makes it possible to significantly reduce the amount of steel required to manufacture products without a loss of force capacity of the steel in the products. The reduced amount of steel required for products improves the economics of construction and reduces the carbon footprint.
