Machining Material Hastelloy X

Hastelloy X, a trademark of Haynes International, is a nickel-based alloy (47% Ni) classified as a nickel-chromium-iron-molybdenum alloy that possesses an exceptional combination of oxidation resistance, fabricability, and high-temperature strength.
It is used on aircraft, furnaces, and chemical process Components such as gas turbine engines and combustion zone components.
Machining Hastelloy is similar to other nickel-based superalloys with moderate hardness (like Inconel 625, for example). It should be machined with positive and sharp cutting edges. Geometries that are suitable for austenitic stainless steel will also work well on Hastelloy. However, it is better to use geometries and grades that are specially designed for superalloys.
The machinability rating of Hastelloy X is about 18%. You can find here machinability values for other superalloys.

Summery:

  • For general Turning of Material Hastelloy X at stable conditions use a grade with a Very Hard substrate and PVD coating.
  • For general Milling use a grade with a Semi Hard substrate and PVD coating.
  • For detailed carbide grades recommendations, check the Below Chart, or use the Grades Wizrad.
  • Recommended Cutting speed range for turning at stable conditions is 200 - 280 [SFM] / 60 - 85 [m/min].
  • Consider using CBN inserts. Although they cost more than twice, they enable increasing the cutting speed by 2-4 times (relative to carbide). Learn More ⇒
  • Recommended Cutting speed range for milling with stable clamping and short overhang is 150 - 200 [SFM] / 45 - 60 [m/min]
  • For detailed cutting speed recomendations, check the Below Table, or use our Speed and Feed Calculator.
