Steel, Corrosion Resistant, Bars, Wire, and Forgings 17Cr 0.52Mo (0.95-1.20C) (SAE 440C) Consumable Electrode Vacuum Melted
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 and having hardness not lower than 58 HRC, but usage is not limited to such applications.
