This alloy is constructed with a balance of different elements, which creates a unique combination that gives it certain characteristics, especially when it comes to its corrosion resistance. The name of this alloy reflects the prominence of some of the elements it contains: the 25% chromium, 22% nickel, and 2% molybdenum. Chromium gives the alloy its resistance to corrosion, enhancing its ability to resist oxidation. In comparison, the other primary elements in the alloy add to the corrosion resistance by supplying physical strength and working with the chromium to be more resistant to corrosive forces.

The chromium also helps to provide increased strength, making 00Cr25Ni22Mo2N (2RE69) a great choice for applications such as aerospace and automotive components, medical implants, and components requiring extended periods of use in corrosive environments. The alloy also provides good formability and weldability, making it very versatile and durable. Additionally, the alloy has been used in applications that require non-magnetic properties.

Chromium provides the alloy with additional fatigue and crack growth resistance, so it is particularly well-suited for applications that are exposed to high loads and a corrosive environment, such as the aerospace and automotive industries. The presence of the molybdenum provides a secondary layer of corrosion resistance that helps to improve the overall corrosion resistance of this alloy. This secondary layer of corrosion resistance helps to protect the alloy from acidic liquids and harsh environmental conditions.

The combination of chromium, nickel, and molybdenum makes 00Cr25Ni22Mo2N (2RE69) a highly dependable alloy for applications that require extended periods of use in corrosive conditions. The combination of the three elements provides an alloy with a high degree of strength and crack growth resistance, with excellent formability and weldability. This combination makes the alloy a great choice for applications such as aerospace and automotive components and medical implants, where extended periods of use in corrosive conditions are often required.

00Cr25Ni22Mo2N (2RE69) is a nickel-chromium-nickel austenitic stainless steel.
