Physical and chemical tests of steel for boilers and ship-plate for the United States Government cruisers, by Pedro G. Salom.
This article gives the conclusions reached by the author from a long series of tests of the steel made for the new cruisers. The average percentage of phosphorus is .039; of carbon .15, and of manganese .38; but the author assumes from the tests that phosphorus to the extent of .075 per cent, is not very injurious to the physical properties of soft steel. He believes that instead of hardening steel, phosphorus tends to destroy homogeneity by preventing the dissemination of the carbon. The results of the tests show the necessity of having some uniformity in the methods of physical tests, and the author suggests chemical analysis. The paper is accompanied by a table giving the results of over 350 tests; it has been reprinted in the Journal of the Franklin Institute for July, 1884.
