Scope

This specification covers an aircraft-quality, low-alloy, heat-resistant steel in the form of bars, forgings, and forging stock. These products have been used typical for parts, such as turbine discs, compressor discs, and fasteners, for service up to 1050 °F (566 °C), but usage is not limited to such applications.
