Part I of this report states the test results for the following steels: W, S-9, S-12, and S-22. The tests of Part I are tension tests run at various temperatures on speciments 24 in long, 12 in wide and 3/4 in thick, having a central internal notch one-quarter of the width of the plate with ends of the notch 0.010 inch wide made by a jeweler's hack-saw. The load was applied in the direction of rolling. The report contains tables giving the load at first visible crack, at maximum load, and at the failure load, together with the energies computed to these loads. Load elongation curves for each specimen tested are included, together with diagrams showing maximum load, vs. temperature and diagrams showing energy to maximum load vs. temperature. The character of the fracture as determined by the percentage of shear failure is also given. The transition temperature zones of these steels on the basis of both energy considerations and the mode of the fracture are reported. Part II of this report describes the aspect ratio program now under way to determine the effect of plate width and thickness on transition temperature. (Author)
