SAE AMS 6267H-2012 (SAE AMS6267H-2012)
Steel Bars, Forgings, and Tubing, 1.2Cr 3.25Ni 0.12Mo (0.07-0.13C) (9310) Electroslag Remelted or Consumable Electrode Vacuum Remelted
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
These products have been used typically for carburized parts requiring high minimum core hardness with a narrow range and subject to stringent magnetic particle inspection standards, but usage is not limited to such applications.
