By the use of the high-temperature and high-speed tensile testing machine montioned in report No. 1 (Tetsu-to-Hagane vol. 41 (1955) No. 5, p. 506-515), the author performed tensile tests of the following combinations in regard to 15 kinds of steels (refer to Table 1) to be used for seamless tubes.
For all of these, the author obtained both the nominal stress-strain curve and the true stress-natural strain curve. The values of deforming stress (at 20% strain) were listed in Table 2. These data conformed to those of other authors already developed.
Among such factors as deforming stress σ, deformation (strain) ε, deforming speed ε and temperature (absolute) Tk, the author obtained the following equation. In this report the above relation was fully discussed.
