17-10Pステンレス鋼の性質

抄録

Several kinds of solution and aging treatments were given in combination to 17-10P stainless steel (17Cr, 10Ni, 0.25P and 0.12C), to investigate its tensile strength (at 600°C) and stress rupture strength (at 600°C), both for smooth and notched specimens. With increasing solution temperature from 1000°C to 1260°C, the tensile strength at 600°C (for both smooth and notched specimens) increased and approached certain values, but the stress rupture time (for smooth specimens) showed a maximum at about 1080°C and then decreased rapidly.
The stress rupture time for notched specimens was somewhat different; the higher the ductility the greater the notch-strengthening tendency.
