shows 434ppm/degC, so the data is not 10% but 300%. Strange, as Young's is one of the more stable, process-resistant, alloy-resistant properties of metal...

Hmmmm.
From your data, I get (1-28.0/27.5)*1/122degC, or 148ppm/degC.
From metengr I get (1-28.8/28.2)*1/70degF, or 304ppm/degF, 170ppm/degC.
From a graph in "Elevated Temperature Modulus Measurements using the Impulse Excitation Technique (IET)", I get 315 ppm/degC.
Throw out the outlier...
Hi,
We have a machined 316 cup, 3" diam x 0.5" long with 0.08" walls. We would like it to be dimensionally stable in the 0-60 degC range (except for expected thermal expansion).
We get about 0.0002" movement in the center (not temperature expansion, but an oil-can distortion of the...
