Steel Tubing, Seamless, 0.95Cr - 0.20Mo (0.33 - 0.38C) (SAE 4135), Normalized or Stress Relieved
This specification covers an aircraft-quality, low-alloy steel in the form of seamless tubing.
This tubing has been used typically for thin wall-thickness sections where minimum tensile strength up to 160 ksi (1103 MPa) is required and where parts may be welded during fabrication, but usage is not limited to such applications.
Data Sets - Support Documents
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.
