Thermal expansionCarbon steel vs stainless steel
(OP)
At the Shigley- Mischke MECHANICAL ENGINEERING DESIGN
a table states that the thermal expansion for carbon steel
is 10.8 E-6 in °C and 6.0E-6 in farenheit from 0 to 100 C
And for Stainless steel this values are
17.3 E-6 °C or 9.6 °F
Does any one know what kind of SS is .
I{m looking for a ferrous alloy to have aboutt more than 50 % Threma expansion coefiecent that the carbon steel at 650 °C
If possible a comercial trade alloy.
Thanks in advance.

RE: Thermal expansionCarbon steel vs stainless steel
This 300 mm diameter round Sae 1010 plates 38 mm thick, will hold a stack of about 100 each Sae 1070 1mm thick to be flattened .
This, can be called sandwich, will be hold by a 40 mm round SAE 4140 threaded bar heat treated as a 12.9 grade bolt.
To build up a increasing compression , I intent to put a spacer over one plate and under the nut that will tighten all the array , this spacer shall be of a material with a different thermal expansion from the others components.
I thought on a aisi 304 hollow bar as it have a thermal exp coefficient about 17E-6 micro mm/meter/°c
and the carbon and alloy steel had about 10e-6 .
My concern is about the behavior of all this array at the 480 C temperature, it will be about 4 hour since this temp is reached.
The task to cope, is to avoid a loss on the compression, so all the 1070 plates are gathered side by side , so they will last flattened when this force is released, of course that it will happen after the eat treatement.
Any comment will be granted.
