Description / Abstract:
Form
This specification covers a premium aircraft-quality, low-alloy
steel in the form of bars, forgings, mechanical tubing, and forging
stock.
Application
These products have been used typically for carburized parts
requiring high minimum core hardness with a narrow range, reduced
distortion and subject to stringent magnetic particle inspection
standards, but usage is not limited to such applications.
Classification
Steel covered by this specification is classified by melting
practice as follows:
Type 1 Electroslag remelted (ESR)
Type 2 Consumable electrode vacuum remelted (VAR)
Unless a specific type is ordered, either type may be
supplied.
