In order to investigate the creep deformation behavior of stainless steel thin sheet belt under high temperature, creep fatigue tests were carried out at high temperature using specimens of SUS305, SUS430 and SUS632. As the results, creep fatigue lives of SUS305 and SUS430 decreased with increasing temperature, and creep fatigue life of SUS632 did not decreasing with increasing temperature. Creep strain of SUS305 was almost equal from 100℃ to 300℃, and increased over 300℃. Creep strain of SUS430 increased with increasing temperature. Creep strain of SUS430 increased from 100℃ to 200℃, and decreased from 200℃ to 400℃.
