Steel Bars, 1.0Cr - 0.20Mo - 0.045Se (0.39 - 0.48C) (4142H Modified), Die-Drawn, 130 ksi (896 MPa) Yield Strength, Free Machining
- Aerospace Material Specification
This specification covers a free-machining, low-alloy steel in the form of round bars 3.50 inches (88.9 mm) and under in nominal diameter.
These bars have been used typically for parts, such as shafts, axles, pins, fasteners, gears, and screw machine parts, which are normally used at hardness of 30 to 36 HRC and which do not require a high degree of ductility, 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.
