Quick Answer: What Is Incoloy 901?

Incoloy 901 (UNS N09901 / W.Nr. 1.4898) is a precipitation-hardenable nickel-iron-chromium alloy specifically developed for components requiring high strength and corrosion resistance at elevated temperatures. By incorporating titanium and aluminum, and maintaining a high nickel content (approx. 42%), Incoloy 901 achieves exceptional creep-rupture strength and mechanical integrity at temperatures up to 600°C (1110°F). It is primarily used for rotating parts in gas turbines, such as turbine discs, shafts, and casings.

Product Overview

Incoloy 901 is a specialized superalloy that bridges the gap between stainless steels and high-nickel superalloys. Its unique chemistry features a balance of iron and nickel, strengthened by the precipitation of the gamma prime phase [Ni3(Al, Ti)] during heat treatment. This makes it significantly stronger than standard austenitic alloys at service temperatures, while the chromium and molybdenum content provides robust resistance to oxidation and localized corrosion.

Key properties include:

• High Tensile & Creep Strength: Maintains structural stability under high load up to 600°C.
• Excellent Oxidation Resistance: Forms a protective scale in high-temperature gas paths.
• Good Fabricability: Can be forged and machined with precision despite its high hardness.
• Microstructural Reliability: Long-term stability in cyclic thermal environments.

Incoloy 901 is widely utilized in Aerospace Propulsion, Industrial Gas Turbines, and High-Performance Automotive applications. Founded in 2012, Shanghai Hangbo Alloy Group Co., Ltd. is an ISO 9001:2015 certified manufacturer delivering precision-forged Incoloy 901 products to over 32 countries worldwide.
