thermal contraction of carbon steel rings
thermal contraction of carbon steel rings
(OP)
Hello !
I am working with thermal contraction of carbon steel rings at temperatures from 1200 K and down to room temperature.
I know the theoretical linear thermal expansion factor of the steels but according to measurements it seems that rings with bigger diameter has a higher "shrinking factor".
Does anybody know what influence the geometric shape and size of the ring has on the thermal contraction?
Thanks in advance,
Ola

RE: thermal contraction of carbon steel rings
delta V = 3* linear COE
Larger diameter, or increased thickness or increased length means greater increase/decrease in change of dimensions.

I have measured the decrease with a special kind of ruler. I'll keep in mind the volumetric expansion. Maybe also the colling down time has some effect.
I'll look into that.
