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
