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 produced by a die-drawing process. AMS6378H results from a Five-Year Review and update of this specification that revises composition analytical methods (3.1), condition (3.2), decarburization (3.3.4), adds tensile testing strain rates (3.3.4.1), prohibits unauthorized exceptions (3.6) and revises reporting (4.4) and Identification (5.2).
Steel Bars 1.0Cr - 0.20Mo - 0.45Se (0.39 - 0.48C) (4142H Modified) Die-Drawn, 130 ksi (896 MPa) Yield Strength Free Machining
