Steel Bars, 1.0Cr - 0.20Mo - 0.045Se (0.39 - 0.48C) (4142H Modified), Die-Drawn, 130 ksi (896 MPa) Yield Strength, Free Machining
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.<p>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.
AMS6378G results from a Five Year Review and update of this specification that revises macrostructure, decarburization and reporting.
