Incoloy Alloy 925, also known as N08925, is an advanced nickel-iron-chromium-based alloy designed to provide superior performance in a variety of corrosive environments. The alloy’s combination of high strength, good workability, and excellent corrosion resistance makes it the material of choice in several industries. In this article, we will conduct a detailed analysis of the composition, properties, and uses of Incoloy 925.
Incoloy Alloy 925 (UNS N08925) – Composition, Properties and Uses
Incoloy Alloy 925 (UNS N08925) – 1. Composition:
The main components of Incoloy 925 include nickel (Ni), iron (Fe), and chromium (Cr). Among them, the high content of nickel gives the alloy excellent corrosion resistance and high-temperature stability. As the base element of alloys, iron provides essential strength and structural support. The addition of chromium further enhances the oxidation and corrosion resistance of the alloy.
In addition, Incoloy 925 also contains key trace elements such as copper (Cu), molybdenum (Mo), and nitrogen (N). The addition of copper helps improve the corrosion resistance of the alloy in reducing acids, while molybdenum enhances the alloy’s resistance to local corrosion such as pitting and crevice corrosion. The slight addition of nitrogen can significantly improve the mechanical properties and corrosion resistance of the alloy.
