Ultimate tensile strength (UTS) data and best-fit correlation (Su) for unirradiated vanadium alloys with 4-5 wt.% Cr, 3-5 wt.% Ti and 0.05 +/- 0.04 wt.% Si. The best fit correlation is recommended to represent the average UTS for V-4Cr-4Ti. The correlation Sud is recommended for design analysis and for determining the limiting stress intensity (Sm) for average primary membrane stresses.
