During this test, one end of an inch-diameter cylindrical test sample is quenched with water and the curing response is measured as a function of distance from the quenched tip.sp.info Hardenability of Steel:the Jominy Test - Materials determined by hardness testing in several areas of a sample, is what hardenability measures. Hardenability also determines the necessary cooling rate, fast or slow, for martensite formation. The Jominy End-Quench test determines hardenability of any variety of steel, and is straightforward due to its simplicity and minimization of variables.
