1. What is UNS N09901?

UNS N09901, or Inconel 901, is a precipitation-hardened nickel-iron-chromium alloy with approximately 42-46% nickel, 12-14% chromium, and additions of molybdenum, titanium, and aluminum, offering outstanding strength and creep resistance at elevated temperatures. Its balanced composition makes UNS N09901 material ideal for gas turbine discs, shafts, and high-temperature fasteners. Compared to UNS N07718, UNS N09901 provides superior creep resistance in high-temperature environments but may require more careful heat treatment.

Gangsteel’s UNS N09901 alloy steel plate is tailored for demanding aerospace applications, providing a robust alternative to nickel alloy steel grades like UNS N06002 and UNS N07080.
