WebCarbon also increases the hardenability of steels by retarding the formation of pearlite and ferrite. However, the effect is too small be be commonly used for control of hardenability. High carbon steels are prone to distortion and cracking during heat treatment, and can be difficult to machine in the annealed condition before heat treatment. WebHardenability is a measure of the ability to harden a steel to a given depth. It is not the same as hardness, which measures a material's ability to withstand penetration by a hard indenter. The factors that displace TTT curves to the right, inhibiting the transformation of austenite to pearlite, also increase the hardenability of the steel.
