Inconel X-750 is a nickel-based heat resistant superalloy (HRSA) material with a machinability rating of 15% and hardness of 32 HRC.
Inconel X-750 has 72% nickel and additional alloying elements per the table below.
The main feature of nickel-based alloys is their excellent strength across a wide temperature range combined with good corrosion resistance. In this sub-group, the material standards also define the allowed hardness range, and hardness is a significant factor affecting the machinability (besides the chemical composition).
Inconel X-750 is among the hardest of the nickel-based alloys, and accordingly has poor machinability of only 15%.
Superalloys should be machined with a positive and sharp cutting edges. Geometries that are suitable for austenitic stainless steel will also work well on HRSA. However, quality manufacturers will have in their catalogs additional geometries that are specifically designed for these challenging materials.
