Abstract : Metallurgical examination including Brinell hardnesses, fracture tests for steel soundness, fracture tests of response to heat treatment, macroetch tests, microscopic examination, V-notch Charpy impact tests on selected plates, chemical analysis and Jominy hardenability was conducted on eighteen plates submitted by Great Lakes Steel Corporation and tested at the Ordnance Research Center as a part of the effect of hardness program. There were six plates each of the three thicknesses 1-1/8, 1-1/4, and 1-1/2 inches. All plates were fairly satisfactorily heat treated. Three plates were of unsatisfactory quality with respect to steel soundness.
