The publication provides yield strength data for different materials (steels, copper, and nickel-base) for temperatures greater than the ones provided in current ASME BPVC IID/Y-1 tables. For this purpose, data from different sources were obtained. The current Y-1 Tables values were not to be affected; therefore, the data had to be fit to those values (customary and metric). This led to bumps in the curves, which were normalized by shifting the data of the current report (in the percent range). Providing smooth curves via a polynomial fit through all data is certainly an alternative, however, this would also affect values in ASME BPVC IID/Y-1 tables. The data provided in this report would allow for such a treatment.
