Metallurgical examination, including Brinell hardnesses, fracture tests for steel soundness, fracture tests for response to heat treatment and macroetch tests, was conducted on each of the twenty-five plates furnished by Republic Steel Corporation. Micrtoscopic examination, chamical analyses and Jominy hardenability determinations were made of selected plates. All plates were uniformly satisfactory with respect to steel soundness and were properly heat treated as revealed by the fibrous manner in which all except those samples of the maximum hardnesses fractured.
