Incoloy Alloy 926, also known as UNS N08926, is a super austenitic stainless steel. This alloy is designed to provide higher corrosion resistance than traditional stainless steel in a variety of corrosive environments, especially those containing halides. Due to its excellent properties, Incoloy 926 has a wide range of applications in multiple industries. In today’s article, we will introduce in detail the composition, properties, and uses of Incoloy 926 (UNS N08926).
Incoloy Alloy 926 (UNS N08926) – Composition, Properties, and Uses
Incoloy Alloy 926 (UNS N08926) – 1. Composition:
The main components of Incoloy 926 include iron (Fe), chromium (Cr), nickel (Ni), and molybdenum (Mo). High levels of chromium and nickel provide basic corrosion resistance. The addition of molybdenum further enhances its corrosion resistance in reducing environments and environments containing halides.
In addition, the alloy also contains copper (Cu), nitrogen (N), and small amounts of other elements. The addition of copper helps improve the alloy’s corrosion resistance in acidic environments, while nitrogen enhances its mechanical properties and resistance to localized corrosion, such as pitting and crevice corrosion.
