    Young's vs. temperature

    I guess. www.outokumpu.cz/documents/1042EN2_Steel%20Grades_Properties.pdf 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... ...L

    Young's vs. temperature

    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...

    Young's vs. temperature

    Hi, We need to compensate 0 to 60degC, so however many temperatures gives us a nice curve fit. Tension alone will work... ...L

    Thermal stability of 316

    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...
