For the heat treater, the concept of hardenability is often more difficult to grasp than that of hardness. Part of the reason for this is that we seldom perform the tests that measure or predict this property in our shops. The reason why it is important to measure the hardenability of steel is to make sure that we are making the right material choice for a specific engineering application. With the supply of raw material coming from multiple worldwide sources, there is renewed emphasis on predicting how a material will respond to heat treating. Let’s learn more.
