SAE AMS 6267G-2007 (SAE AMS6267G-2007)
Steel Bars, Forgings, and Tubing, 1.2Cr 3.25Ni 0.12Mo (0.07-0.13C) (SAE 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.
