Book excerpt: Excerpt from Technologic Papers of the Bureau of Standards, Vol. 203: Influence of Phosphorus Upon the Micro-Structure Structure and Hardness of Low-Carbon, Open-Hearth Steels, November 21, 1921 In connection with an investigation made several years ago into the effect of varying phosphorus content upon the endurance qualities of low-carbon steel when severely cold worked, as in stamping, drawing, pressing, upsetting, and bending, Dr. J. S. Unger prepared two series of ingots, one of basic open-hearth steel and the other of acid open-hearth steel, all having the same general composition, but with the phosphorus content varying from 0.008 to 0.11 per cent, and which comprises the range of phosphorus content usually found in acid open-hearth and acid Bessemer steel. These steel ingots were rolled down into the usual billets, slabs, and sheet bar preparatory to the formation by cold work of the various products upon which the tests were made. These steels were given no other than the customary heat treatment accorded ordinary soft steels during the process of fabrication. Through Dr. Unger's kindness, a small quantity of material in the form of 1-inch rounds from the two series of ingots was made available for this study. There appears to be scant information of a systematic nature in the published literature with regard to the influence of varying amounts of phosphorus, especially within the limits usually found for this element in open-hearth and Bessemer steel, upon the microstructure and physical properties of low-carbon steel as developed by heat treatment. D'Amico published in 1913 the results of an investigation carried out on the microstructure, hardness, mechanical, and magnetic properties as developed by heat treatment in a series of 12 low-carbon steels, made by the electric process, to which phosphorus had been added, so that the resulting phosphorus content varied from 0.012 to 1.242 per cent. Only two of his steels come within the range of phosphorus content covered in this investigation. Dr. Unger stated that in his investigation the effect of heat treatment was not studied, inasmuch as soft steels are rarely heat treated, though he made a few tensile and other tests on some heat-treated bars.
