Abstract : This 1944 report discusses a metallurgical examination, including fracture tests for steel soundness and response to heat treatment, Brinell hardness tests, macroetch tests and microscopic examination, which was conducted on sections from six 1 inch thick homogeneous plates. Steel soundness was satisfactory on all but one plate. Poor shock properties, as denoted by crystalline fractures, were observed on all plates at hardnesses above 340 Brinell.
