A cross section of the surface shall be prepared in accordance with ASTM E1077 and examined metallographically at a magnification not to exceed 100X. Optical indications of decarburization shall not show a layer of complete (ferrite) or partial decarburization exceeding the limits of Table 3.
The total depth of decarburization shall be determined by a traverse method using microindentation hardness testing, in accordance with ASTM E384, conducted on a hardened but untempered specimen protected during heat treatment to prevent changes in surface carbon content. 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. 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 3.
The producer of bar, forgings, and rings shall furnish with each shipment a report showing the producer identity,country where the metal was melted (e.g, final melt in the case of metal processed by multiple melting operations),results of composition, macrostructure, hardenability, and frequency-severity cleanliness rating for each heat and,if measured for average grain size of each lot and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, heat, and lot numbers, AMS6382R, product form and size or part number, and quantity. If forgings are supplied, the size and melt source of stock used to make the forgings shall also be included. If the grain size requirement of 3.3.2.2 is met by the aluminum, vanadium, and/or columbium content, the aluminum, vanadium, and/or columbium content shall be reported and a statement that the chemistry satisfies the grain size requirement shall be included.
The producer of stock for forging and flash-welded rings shall furnish with each shipment a report showing the producer identity, country where the metal was melted (e. g., final melt in the case of metal processed by multiple melting operations), and the results of tests for composition, macrostructure, hardenability, and frequency-severity cleanliness rating of each heat. This report shall include the purchase order number, heat number, AMS6382R,size, and quantity.SAE AMS 6382R pdf free download.
