SAE AMS 5898A-2001 (SAE AMS5898A-2001)
Steel, Corrosion Resistant, Bars, Wire, and Forgings 15.2Cr 1.0Mo 0.40N (0.28 - 0.34C) Consumable Electrode Melted Under Pressure ( Reaffirmed: Apr 2006 )
This specification covers a premium aircraft-quality, corrosion-resistant steel in the form of bars, wire, forgings, and forging stock. These products have been used typically for anti-friction bearing components requiring resistance to both corrosion and wear with hardness not lower than 58 HRC after hardening and tempering, but usage is not limited to such applications.
