TWELVE INCH FLAT PLATE TESTS.
Abstract
The report contains an account of the testing of the 'A', 'C', 'Bn', 'Br', 'Du' and 'E' steels. The tests described are tension tests run at various temperatures on specimens 24in long, 12in wide and 3/4in 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 hacksaw. The load was applied in the direction of the rolling. This program was undertaken because it was believed that tests made under standardized conditions would furnish additional information regarding the behavior of these steels, and would provide a standard that could be used to judge the efficacy of tests of small sized specimens adapted for use as acceptance tests. The report contains tables giving the load at first visible crack, at maximum load, and at ultimate load, together with the energies computed to those loads. Load-elongation curves for each specimen tested are included, together with diagrams showing maximum load, plotted with temperatures as abscissas, and diagrams showing energy to maximum load plotted with temperatures as abscissas. The transition temperature zones of these steels based on the 12in wide plate tests are reported based on energy considerations and on the mode of the fracture. (Author)
