Abstract:

Metallurgical examination, including Brinell hardness readings, fracture tests for steel soundness and response to heat treatment, and macroetch tests, was conducted on eawch of the twenty samples furnished by the Standard Steel Spring Company. Microscopic examination and chemical analyses were made of selected samples. All samples except 4273 D fracture were satisfactory with respect to steel soundness. Fourteen of the samples responded to heat treatment satisfactorily as revealed by the fibrous manner in which they fractured. Of the remaining six of maximum hardnesses, three were completely crystalline whereas the other three had varying amounts of crystallinity.
