16、3.2.2 PlateHot rolled, annealed, sub-critically annealed or normalized if necessary, and descaled. Bar shall not be cut from plate (also see 4.4.1).SAE INTERNATIONAL AMS5085J Page 3 of 53.2.2.1 If allowed by the purchaser, cold rolled, annealed, sub-critically annealed or normalized if necessary, an
17、d descaled as necessary, having hardness not higher than 85 HRB, or equivalent (see 8.2).3.3 PropertiesThe product shall conform to the following requirements; hardness and bend tests shall be performed in accordance with ASTM A370:3.3.1 BendingThe product shall withstand, without cracking, bending
18、at room temperature through an angle of 180 around a diameter equal to twice the nominal thickness of the product with axis of bend parallel to the direction of rolling.3.3.2 DecarburizationDecarburization shall be evaluated by one of the methods of 3.3.2.1 or 3.3.2.2.3.3.2.1 Metallographic MethodA
19、cross section taken perpendicular to the surface shall be prepared, etched, and visually examined metallographically at a magnification not to exceed 100X. The product shall not show a layer of complete (ferrite) or partial decarburization exceeding the limits of Table 2.3.3.2.2 Hardness Traverse Me
20、thodThe total depth of decarburization shall be determined by a traverse method using microindentation hardness testing in accordance with ASTM E384, at a magnification not exceeding 100X, conducted on a hardened but untempered specimen protected during heat treatment to prevent changes in surface c
21、arbon content. Tempering is generally not recommended, but if tempered, the tempering temperature shall be not higher than 300 F (149 C). Depth of decarburization is defined as the perpendicular distance from the surface to the depth under that surface where there is not further increase in hardness
22、. Such measurements shall be far enough away from any adjacent surface to be uninfluenced by any decarburization on the adjacent surface. Acceptance shall be as listed in Table 2.

24、2.3 When determining the depth 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.3.3.2.4 In the case of dispute, the total depth of
