Such measurements shall
29、be far enough away from any adjacent surface to be uninfluenced by any decarburization on the adjacent surface. In case of dispute, the depth of decarburization determined using the microhardness traverse method shall govern. SAE INTERNATIONAL AMS5655F Page 5 of 7 3.4.2.4.4.1 When determining the de
30、pth of decarburization, it is permissible to disregard local areas provided the decarburization of such areas does not exceed the above limits by more than 0.005 inch (0.13 mm) and the width is 0.065 inch (1.65 mm) or less. 3.4.3 Forging Stock When a sample of stock is forged to a test coupon having
