By the use of the high-temperature and high-speed tensile testing machine mentioned 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. [table] 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. σ=k・ε^n・ε^m・e^<A/TK> In this report the above relation was fully discussed.
