AMS6408F: Steel, Hotwork Tool, Bars, and Forgings and Forging Stock 5.25Cr - 1.5Mo - 1.0V (0.35-0.45C) (H-13) Electroslag Remelted (ESR) or Consumable Electrode Vacuum Arc Remelted (VAR) Annealed

Scope

Content: This specification covers a premium aircraft-quality, low-alloy steel in the form of bars and forgings 25 square inches (161 cm²) and under, and forging stock of any size.

Rationale

Content: AMS6408F is the result of a Five-Year Review and update of the specification. The revision updates the title to match the scope, updates compositionn reporting (3.1.1), revises macrostructure testing requirements (3.4.1.1, 8.7), prohibits unauthorized exceptions (1.1, 3.4.5, 3.7, 4.4.4, 8.5), revises decarburization test methods (3.4.3.4), adds pyrometry and updates heat treatment for response to heat treatment (3.4.4), adds instruction for forging stock (3.4.4.1.2, 4.4.3), advises on surface finish (8.4), and allows prior revisions (8.6).
