Cast Iron: Properties, Processing and Applications

To produce cast iron, the iron must be extracted from iron ore. The ore is smelted in a blast furnace where it separates into pig iron and slag. The furnace is heated to around 1800 degrees Celsius in an oxygen atmosphere and the slag formed rises to the top and can be removed. The molten pig iron below contains around 3 wt.% – 5 wt.% carbon.

Analysis of hardness and heat treatment process of high chromium cast iron …

When high chromium cast iron is treated at 1000 ° C, carbon has high solubility and stability in austenite. When equilibrium is reached, only a small amount of secondary carbides are precipitated from austenite. When it is cooled to room temperature, part of austenite is transformed into martensite, and the rest of austenite remains.
