C90300/SAE 620
- Typical Uses


Characteristics:
Hard, strong, ductile; corrosion resistant to seawater and brine; wear resistance; good resistance to pounding; good machining properties similar to SAE 62 but easier to work in foundry; requires reliable lubrication, good alignment, and a shaft hardness of 300 - 400 Bhn.

Uses:
Heavy loads and low speeds; bushings for aircraft landing gear; machine-tool bearings; trunion bearings; trolley wheels; seal and piston rings; pump impellers; steam fittings, valve components; wrist-pin bushings for air compressors.

C90500/SAE 62
- Typical Uses


Characteristics:
Hard, strong corrosion resistance, especially to sea water, wear resistance, high resistance to pounding; difficult to broach but can be bored or reamed; required good, reliable lubrication and a shaft hardness of 300-400 Bhn.

Uses:
Heavy loads and low speeds; piston-pin bushings; valve guides; rolling-mill bearings; rocker-shaft bushings for internal combustion engines; worm gears, bridge parts and expansion bearings; pilot bearings, roll bushings, linkage bushings for machine tools.
