This 1944 report discusses a metallurgical examination, including Brinell hardness surveys, fracture tests for steel soundness and fibre, and macroetch tests, which was conducted on each of the six plates furnished by Standard Steel Spring Company. Microscopic examination was made on two plates and a chemical analysis taken of one. All plates were satisfactorily heat treated as revealed by the fibre fracture test.
