For simplified design of components operating at high temperatures, it is recommended to design in the NC (no creep) or NEC (negligible creep) temperature regimes of the material. To do judgement for this, a negligible creep temperature (TNEC) curve, which is set as accumulated creep time and temperature, should be needed. In this paper, concept of the TNEC curve was preliminarily described, and then, the TNEC curves for Type 316L(N) stainless steel which is anticipated to be used as high-temperature fuel cell material were generated by using three reference stress values, and their curves were compared with the RCC-MRx curve. It was found that the TNEC curve applied as a reference stress of average yield strength 1.5 Rp0.2 (moy) showed good match with the RCC-MRx one.
