When we do cardonitriding or casehardening operation for a plain carbon steel the case depth, hardness & microstructure are not alike why and what are the basic thing, which makes such a difference.


Usually that will depend on the time and temperature, as well as chemical composition of the furnace atmosphere you are using.

If these variables are not kept well controlled, they may cause very different results. Please note that time and temperature are correlated, the more temperature, the less time and lesser diffusion control.
