Nimonic 901 is a Nickel-based heat resistant superalloy (HRSA) material with a Machinability rating of 13% and Hardness of 36 HRC. Nimonic 901 has 43% nickel and additional alloying elements. 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). Nimonic 901 is among the hardest of the nickel-based alloys, and accordingly has poor machinability of only 13%.
