What is Incoloy?

Incoloy alloy is a general term for a series of high-temperature alloys with a high iron content. Depending on the ratio of nickel, chromium and iron, Incoloy alloy can be nickel-iron-chromium alloy, iron-nickel-chromium alloy or iron-chromium-nickel alloy.

Chemical composition of Incoloy

There are many grades of Incoloy alloy, mainly for two reasons:

First, because Incoloy alloy sacrifices performance to a certain extent, different fields need to focus on more detailed performance, so different elements are added to Incoloy alloy to achieve different performance characteristics, and different grades are formed.

Second, Incoloy alloy is a low-cost alloy, and different iron contents also form different grades of alloys, giving people more choices at different costs.

Below are the common Incoloy grades:

Mechanical properties of Incoloy

Based on the difference in microstructure, Incoloy alloys can be divided into two categories: solid solution strengthened alloys and precipitation strengthened alloys.

Among these two categories, precipitation strengthened alloys can obtain much higher strength than solid solution strengthened alloys through aging treatment. The following table compares the mechanical properties of two typical alloys:

Physical properties of Incoloy

Due to the reduced nickel content and increased iron content in Incoloy alloy, its density is also lower than that of Inconel alloy. This also reduces the cost of Incoloy alloy to a certain extent. The following table compares the density of common Inconel alloy and Incoloy alloy:

Conclusion

Incoloy is a high-temperature alloy with a high iron content. It can be regarded as an alloy with a reduced nickel content based on Inconel. Its price is cheaper than Inconel alloy, so it can replace some application scenarios of Inconel alloy at a lower cost.
