Determination of Long-Term Creep Properties for 316H Steel Using Short-Term Tests on Pre-strained Material

Abstract Determination of long-term creep rupture properties for 316H steel is both costly and time-consuming given the level scatter in data would need substantial number tests to be performed. The primary objective this study estimate cross-weld (XW) as-received (AR) stainless by performing accelerated on pre-compressed (PC) material. In work, uniaxial have been performed XW specimens results used establish a correlation with test PC Moreover, tensile at room temperature 550 °C examine pre-conditioning effects mechanical response Similar power-law found strain rate time behaviour specimens. It also has that ductility points obtained from fall upon estimated trend AR material when are correlated applied stress normalised 0.2% proof stress. show can much shorter scales simply state.
