Machinability

  • China 303 Stainless steel has excellent machinability. Machining can be enhanced by adhering to the following rules:
  • Cutting edges must be kept sharp. Dull edges cause excess work hardening.
  • Cuts should be light but deep enough to prevent work hardening by riding on the surface of the material.
  • Chip breakers should be employed to assist in ensuring swarf remains clear of the work
  • Low thermal conductivity of austenitic alloys results in heat concentrating at the cutting edges. This means coolants and lubricants are necessary and must be used in large quantities.

Applications

  • China 303 Stainless steel is used in applications that require parts to be heavily machined. These applications include:
  • Nuts and bolts
  • Screws
  • Gears
  • Aircraft fittings
  • Bushings
  • Shafts
