The Hardenability Of Steel

Hardenability involves a rapid transition from a state of 100% austenite to a high percentage of martensite.
Note - Hardenability should not be mistaken for hardness.
* Hardness is the measure of a material's resistance to indentation or deformation. while hardenability is the ability of steel to form martensite.
* The Jominy end quench test is used to test the hardenability of steel.
The relationship of hardness to distance from the quenched end is an indication of its hardenability.
- The major factors that affect hardenability include:
• Carbon content of the steel
• Austenite grain size
• Alloying element.
Other factors that can affect hardenability include the geometry of the specimen and the quenching medium used.

Hello from Turkey. The critical cooling rate used in the field of heat treatment is related to hardenability. If the TTT diagram of a steel is close to the right side, a high hardness microstructure can be achieved even at slower critical cooling rates. This depends completely on the chemical composition of the steels (%C, %Ni,%Mo,%Mn,%Cr)
