NOTICEThis document is intended to replace F
6、ederal Specification QQ-A-200E. The original issue and revision A of AMS-QQ-A-200 were taken directly from Federal Specification QQ-A-200E/GEN, Amendment 1, and contained only minor editorial and format changes required to bring it into conformance with the publishing requirements of SAE technical s
7、tandards. This revision B changes the heat treatment specification MIL-H-6088 (cancelled) to AMS 2772 (the superseding document) to ensure that the vital heat treat parameters used for heat-treat-response-test samples conform to parameters used for heat treatment of parts (See 6.6).The original Fede
8、ral Specification was adopted as an SAE standard under the provisions of the SAE Technical Standards Board (TSB) Rules and Regulations (TSB 001) pertaining to accelerated adoption of government specifications and standards.
