AMS2374F Quality Assurance Sampling and Testing Corrosion- and Heat-Resistant Steel and Alloy Forgings

AMS2374F is the result of a Five-Year Review and update of the specification. The revision separates heat and lot definitions (3.3.2 and 3.3.3), reorganizes and updates requirements for forging classes (3.3.4), adds reporting of composition note (3.3.5.2.1), updates specimen requirements (3.3.5.2.2), adds strain rate requirement for tensile tests (3.3.5.2.2.3), adds impact and fracture toughness testing (3.3.5.2.3, 3.3.5.2.4), addresses when more stringent NDT has been performed (3.3.5.2.7), and updates retesting requirements (3.3.6).
