AMS6274S: Steel, Bars, Forgings, and Mechanical Tubing 0.50Cr - 0.55Ni - 0.20Mo (0.18 - 0.23C) (SAE 8620) - 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 bars, forgings, mechanical tubing, and forging stock.

Rationale

Content: AMS6274S results from a Five-Year Review and update of this specification. The update revises analytical methods (3.1), prohibits unauthorized exceptions (3.6, 4.4.4, 5.2.1, 8.7), revises macrostructure requirements (3.3.1, 8.9), adds reduced testing per AMS2301 (4.2.1, 4.4.1, 4.4.3, 4.4.5), and modifies hardenability (3.3.3).
