Steel, Bars, Forgings, and Tubing 1.2Cr 3.25Ni 0.12Mo (0.07 0.13C) (SAE 9310) Vacuum Consumable Electrode 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 critical carburized parts requiring high minimum core hardness with a narrow range and subject to very rigid magnetic particle inspection standards, but usage is not limited to such applications.
