A crack observation report details a crack found during a hot forging process of a part on September 3, 2021. Microscopic images show the crack is regular without branches, suggesting it originated from a seam or lap during the steel rolling stage rather than from forging. The crack was between 0.400 and 0.620 mm deep.
