Regardless of whether the cut parts are preheated, slow cooling reduces the risk of cut edge cracking. Slow cooling can be achieved if the parts are stacked together while still warm from the cutting process and then covered with an insulating blanket, allowing the parts to gradually cool down to room temperature.

Slow cooling by stacking the hot parts and covering them with insulating blanket.
