What Is Interstitial Steel?

Interstitial Steel

Interstitial steel refers to a type of steel alloy in which certain elements, such as carbon or nitrogen, occupy the interstitial spaces between the atoms of the steel’s primary metal (usually iron). These elements are added in small amounts and can significantly influence the properties of steel, such as enhancing its strength, hardness, or resistance to wear. The interstitial elements do not form separate compounds but remain within the gaps between the iron atoms, leading to changes in the material’s microstructure.
