How Is Hardenability Calculated

The hardenability of a ferrous alloy is measured by a Jominy test: a round metal bar of standard size (indicated in the top image) is transformed to 100% austenite through heat treatment, and is then quenched on one end with room-temperature water. … This information is plotted on a hardenability graph.

How do you calculate hardenability of steel?

1. CE = Carbon Equivalent.
2. Pcm = Critical Metal Parameter (Just a different form of a CE.)
3. %C = Percentage of Carbon in the material.
4. %Mn = Percentage of Manganese in the material.
5. %Cr = Percentage of Chromium in the material.

What does hardenability mean in steel?

The hardenability is defined as the ability of the steel to partially transform from austenite to martensite at a given depth below the end surface, when cooled under a given condition.
