Aerospace Stainless Steel Precision Machining

Aerospace stainless steels including 15-5PH, 17-4PH, and 300-series provide corrosion resistance and strength for fasteners, fittings, and corrosion-critical components. Machining requires attention to work hardening and proper heat treatment.

Why Aerospace Requires Stainless Steel Aerospace Machining

  • Corrosion resistance for external components
  • Strength and hardness for fasteners
  • Cryogenic properties for space applications
  • FDA/biocompatibility for human-rated systems
  • Magnetic properties for specific applications

Typical Applications

Fasteners and hardware
Fittings and adapters
Valve components
Exhaust system parts
Cryogenic components
Medical aerospace crossover

Materials Commonly Machined

17-4PH (H1025, H1150)15-5PH304/304L316/316L321Custom 455

Technical Considerations

  • Sharp tooling essential to prevent work hardening
  • Adequate depth of cut - no light passes
  • Rigid setups minimize chatter
  • High-pressure coolant improves tool life
