The producer of the product shall furnish with each shipment a report stating that the product conforms to the composition and showing the numerical results of tests on each inspection lot to determine conformance to the tensile requirements and stating that the product conforms to the other technical requirements. This report shall include the purchase order number,inspection lot number, AMS4144G, size or part number, and quantity. The report shall also include the identity of the producer, product form, and the size of the mill product.
When material produced to this specification is beyond the sizes allowed in the scope or tables, or other exceptions are taken to the technical requirements listed in Section 3 (see 5.1.1), the report shall contain a statement“This material is certified as AMS4 144G(EXC) because of the following exceptions:” and the specific exceptions shall be listed.
If any specimen used in the above tests fails to meet the specified requirements, disposition of the product may be based on the results of testing two additional specimens for each original nonconforming specimen. Retest specimens shall be taken as close as possible to the same location in the same forging or rolled ring or from a second forging or rolled ring from the same lot as was the original unacceptable specimen. F ailure of any retest specimen to meet the specified requirements shall be cause for rejection of the product represented. Results of all tests shall be reported.
Should not be lower than 115 HB/10/500 or 122 HB/10/1000, or equivalent, determined in accordance with ASTM E10, but forgings and rolled rings shall not be rejected on the basis of hardness if the tensile property requirements are met. Hardness has been used to verify that product is properly processed, but an“out-of-range hardness number” is not always indicative of product with“out-of-specification tensile strength”. Further analysis including material composition verification, heat treat process parameter review, and/or tensile property measurement on product with out-of-range hardness may be necessary.SAE AMS 4144G pdf free download.
