AN ATTEMPT TO FIND THE AMOUNT OF PHOSPHORUS IN THREE SAMPLES OF STEEL
Journal of the American Chemical Society
OMETHING over a year and a half ago, in connection with s the preparation of a method for determining phosphorus in steel, to be used as a part of the specifications on which steel is bought, for the use of the Pennsylvania Railroad Company, we deemed it essential to know pretty accurately, the amount of phosphorus in each of three different samples of steel. The use made of the results finally obtained from these steels, is given in our paper, ' On Some Points in the Determination of
... nation of Phosphorus in Steel by the Volunietric Method," and what follows here, is an account of the various efforts made to get the desired information. It will be observed before we have finished, that what at first seemed a very sinipIe thing, proved in the end to be a very difficult affair, and that after all the work done on the subject, the final result is still not entirely free from doubt. The three samples of steel were as follows: No. I was boiler plate made by the open hearth process, and containing presumably about 0.15 per cent. of carbon, and less than 0.05 per cent. of phosphorus. No. 2 was a piece of a locomotive driving tire, made by the open hearth process, and containing presumably from 0.50 per cent. to 0.60 per cent. of carbon and 1 Read at the Baltimore meeting, December 28, 1893.
