Fixture design
(OP)
I need to design a heat treatment fixture, my problem being that I need to work out size achieved at a tempreture of 700deg C for Stainless 316. I can only get the coefficient of expansion for this material up to 500deg. From that data it would appear to be 0.0000195
I know its not a Ug question but any advise would be much appreciated.

RE: Fixture design
What a coincidence, I'm also designing a heat treat fixture (but not using 316 ss). www.matweb.com tells me that the CTE of 316 austenitic SS is non-linear, which is to say that it increases as you get to higher temps. Not sure if this is an issue for you or not. http
Here's a data sheet that goes up to 871C (1600F). As you can see, there's some change but not a ton between the two CTE's listed. If your fixture is larger then of course you can expect more growth. Hope this helps.
