Can a thin stainless steel plate warping and unwarping in a gas oven due to temperature gradients break at some point?

[This is in continuation of a previous question:](https://chemistry.stackexchange.com/questions/163940/can-a-plain-sheet-of-stainless-steel-adhering-to-the-316-grade-be-regarded-as-fo)


I have a specially cut 316 stainless steel plate, 345mm diameter \* 2mm thicknesses, used in a butane pizza oven that can reach 500 degrees Celsius as a base for the pizza dough.


The plate doesn't seem to warp at all during the warm up period, but when I place dough onto it the plate's sides warp upwards a centimeter or two. I suppose this is because the dough cools the upper side of the plate too quickly and that causes it to contract asymmetrically.


When the pizza is removed the plate seem to flatten out pretty quickly. Will such cyclic deformation pattern damage the integrity of the material in the long run?




No, the temperature differences are relatively small in a home oven. It will distort but not crack. Thermal fatigue can be caused near temperatures like 1600 F over thousands of cycles. Heat-treatment containers are typically nickel alloys which have physical properties very similar to 316 ( austenitic structure). They can be cycled to very high temperatures ( 1800 F) every day for years before possibly cracking.
