AMS5737R is the result of a Five-Year Review and update of the specification. The revision revises the Title to match the Scope, clarifies size limits and prohibits exceptions (see 1.1, 3.5.4, 3.8, 4.4.2, 5.2.1, and 8.6), updates composition testing and reporting (see 3.1 and 3.1.1), limits cutting bar from larger products (see 3.3.1.1.3 and 4.4.3), adds option for continuous heat treatment (see 3.4.3), updates tensile test requirements including strain rate control during testing (see 3.5.1.1), adds quality requirements (see 3.6.1 and 8.4), provides for forging stock properties (see 4.4.4 and 8.7), requires reporting of country of origin (see 4.4), and allows the use of prior revisions (see 8.5).
