Steel Bars, Forgings, and Tubing 4.0cr 4.25mo 1.0v (0.77-0.85c) Premium Aircraft-Quality for Bearing Applications Consumable Electrode Vacuum Melted
- Aerospace Material Specification
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
These products have been used typically for critical parts, such as bearings, operating under heavy loads and high speeds at moderate temperatures and subject to very rigid inspection standards, 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.
