Scope
This specification covers an aircraft-quality, low-alloy steel in the form of bars and forgings.
Rationale
AMS6327L results from a Five-Year Review and update of this specification that allows the use of grain refiners (3.1.1), revises decarburizaion testing (3.4.3.3), adds tensile testing strain rate (3.4.4.1) and agreement on properties outside range (3.4.4.2), and revises quality (3.5.2), reporting (4.4), and identification (5.2).

Issuing Committee
AMS E Carbon and Low Alloy Steels Committee
The committee of Carbon and Low Alloy Steels, AMS Committee E, shall prepare, coordinate, and revise documents related to carbon and low alloy steels technology, such as steel cleanliness and steel quality assurance sampling, through the participation of metals suppliers, users, and interested government agencies. Committee activities shall provide a forum for the cooperative interchange of ideas and experience of the participants, resulting in the publication of specifications that embody sound, established aerospace industry practices and requirements to serve the suppliers and customers of aerospace materials.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
