Scope
This specification covers established inch/pound manufacturing tolerances applicable to low-alloy steel bars ordered to inch/pound dimensions. These tolerances apply to all conditions, unless otherwise noted. The term “exclusive” is used to apply only to the higher figure of the specified range.
Rationale
AMS2251J results from a Five-Year Review and update of this specification that adds applicable documents (Section 2) and corrects significant figures in Table 7.

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.
