Description / Abstract:
Form
This specification covers an aircraft-quality, low-alloy steel
in the form of bars, forgings, and forging stock.
Application
These products have been used typically for carburized parts
that require high minimum core hardness and allow wide hardness
range in sections 0.375 inch (9.5 mm) and under in nominal
thickness, but usage is not limited to such applications. The core
may or may not be machinable after hardening.
