Abstract : Twenty-four plates were received from Watertown Arsenal. These plates were approximately 18 inch x 18 inch and of the thickness listed in table I, which also includes the chemical analysis, the latter being rather uniform for the entire lot of plates. The surfaces of the plates in general were in fairly good condition having only small thin films of oxide on them. In a few cases the surfaces were marred by grooves - probably caused by rolling - but these defects prevailed on one side only. The plates as they arrived were packed in grease and in order to remove this, a process of annealing followed by grease-solvent cleaning was applied in order to produce a surface which could readily be pickled. The pickling bath was composed of a 10 percent solution of sulphuric acid, the bath being equipped with an electric heating coil the purpose of which was to hasten the process of removing the oxide and to produce the desired surface for carburization. After pickling the entire lot of plates were set aside as experimental plates for the heat treatment investigation and other experimental work. The remaining eighteen plates were to be prepared for the ballistic tests.
