Rationale: AMS6454G is the result of a Five-Year Review and update of the specification. The revision clarifies composition reporting (see 3.1.1), updates heat-treatment conditions consistent with similar specifications (see 3.3), provides for both the producer and purchaser agreement on condition (see 3.3.3), updates Jominy testing requirements (see 3.4.4), revises decarburization testing requirements (see 3.4.5), and prohibits unauthorized exceptions (see 3.7, 4.4.2, and 8.5).
