CNC Machining with Inconel and Hastelloy

In the demanding world of precision manufacturing, material selection is paramount. For components operating in extreme environments—be it scorching temperatures, corrosive chemicals, or highpressure applications—standard alloys like aluminum or steel fall short. This is where superalloys, specifically Inconel and Hastelloy, come into play. Mastering the CNC machining of these highperformance materials is a specialized skill that sets toptier manufacturers apart and delivers unparalleled value to clients in aerospace, oil & gas, chemical processing, and energy sectors.

Understanding the Challenge: Why Machining Superalloys is Difficult

Inconel and Hastelloy are nickelchromiumbased superalloys renowned for their exceptional properties. They maintain incredible strength at elevated temperatures (Inconel is a champion in this regard) and offer superb resistance to oxidation and a wide range of corrosive media (a key strength of the Hastelloy family). However, these very properties that make them ideal for enduse also make them notoriously difficult to machine. They are prone to work hardening during the cutting process, are abrasive to tooling, and have low thermal conductivity, which leads to excessive heat concentration at the cutting toolworkpiece interface.
