Austenite
Austenite is a solid solution of carbon in iron that forms at high temperatures, typically above 727°C (1,341°F). It is a face-centered cubic (FCC) structure, which allows for a higher solubility of carbon compared to other forms of iron, such as ferrite. Austenite is non-magnetic and is crucial in the production of various steel grades.
In the context of steel manufacturing, austenite plays a vital role in determining the material's properties. When cooled, austenite can transform into other microstructures, such as martensite or ferrite, which significantly influence the strength, hardness, and ductility of the final product.
