Hi all,

Any leads on where I can find some low temp data for youngs modulus of ASTM A276 316/316LSS round bar (cold drawn > 0.5" OD)?
Specifically looking for -90°C, but anything close or lower would be fine and we will just interpolate.
Data that I've found so far only goes down as low as +20°C.
Thanks.

How accurate of data are you looking for?
Have you compared various sources at 20C and looked at the variations?
If you need good data at -90C you will need to arrange to have testing done.
When you measure modulus there are two ways to do it.
Acoustically, the speed of sound in a metal is directly linked to the modulus.
This is fast and simple.
Or measure in tension. You make what looks like a tensile coupon and you load it to ~2/3 Yield, unload part of the way, and re-load.
When you run these cycles you should get a bunch of parallel lines.
This is very hard to do on SS because it yields at such low loads, way below the engineering yield.

P.E. Metallurgy, consulting work welcomed
 
Thanks Ed / Swinny.

Data didn't need to be super accurate, just looking to run some natural frequency estimations at -90°C.

I did search on here for the data that Swinny linked to, but had a brain fart and used "low temp" instead of cryogenic..... lol.

Cheers for your help as usual.
