AMS6323N: Steel, Mechanical Tubing 0.50Cr - 0.55Ni - 0.25Mo (0.38 - 0.43C) (SAE 8740) - Material Specification

Features

Issuing Committee: AMS E Carbon and Low Alloy Steels Committee

Scope

Content: This specification covers an aircraft-quality, low-alloy steel in the form of mechanical tubing.

Rationale

Content: AMS6323N is the result of a Five-Year Review and update of the specification. The revision prohibits unauthorized exceptions (3.6, 4.4.3, 8.7), updates composition and reporting requirements (3.1, 3.1.2), acknowledges that there is no specific condition for this material (3.2, 8.8), updates macrostructure requirements consistent with other specifications (3.3.1, 8.8), modifies jominy requirements (3.3.3), updates decarburization requirements (3.3.4.4), acknowledges periodic testing per AMS2301 (4.2.1, 4.4.2), adds a stock removal note (8.4), and allows prior revision (8.6).
