Steel Bars, Forgings, and Tubing, Nitriding, 1.4Cr - 1.2Mo - 0.3V (0.29 - 0.36C), Double Vacuum Melted, Premium Aircraft-Quality for Bearing Applications
This specification covers a nitriding grade of premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. These products have been used typically for nitrided 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.
