UNS N09901 alloy steel plate, also known as Inconel 901, is supplied by Gangsteel, a leading stainless steel supplier in China. Renowned for its high strength, creep resistance, and good corrosion resistance up to 760°C (1400°F), this precipitation-hardened nickel-iron-chromium alloy is ideal for aerospace, gas turbines, and high-temperature structural applications.
Gangsteel offers UNS N09901 plate, sheet, bar, and custom components, meeting ASTM B637 and ASME SB-637 standards. This page provides detailed insights into the UNS N09901 chemical composition, mechanical properties, equivalent materials, specifications, applications, and competitive UNS N09901 price per kg. Explore our nickel alloy steel grades for related alloys like UNS N06625, UNS N07718, and UNS N08810.
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.
