Applications of Hastelloy X™

• Chemical process industry
• Metallurgical industry
• Jet components, including:
  • Engine parts
  • Aircraft nozzle vanes
  • Cabin heaters
  • Tail cones
  • Collector rings

Machinability of Hastelloy X™

• Machine in wrought and cast forms
• Use plenty of cutting fluid
• Cut at low speeds
• Grind high-speed cutting tools in lathe and turning operations to 6-10° back rake, 5-8° side clearance, 8-10° front clearance, 8-14° cutting edge angle, 10-15° lead angle
• High-speed steels cutting speeds:
  • 25-40 sfpm; feed of 0.003-0.008 in/rev. for turning
  • 20-45 sfpm; feed of 0.003-0.007” for drilling
  • 10-20 sfpm for tapping
  • 25-40 sfpm for milling
  • 20-60 sfpm for reaming
  • Work at higher speeds and use smaller angles with carbide-tipped tools

Workability of Hastelloy X™

• Annealing produces ideal properties for fabricating sheets
