The most commonly used method for determining hardenability is the end quench test developed by Jomini and Boegehold. The details of the test are covered in IS : 3848 – 1981 and ASTM A 255. • In this test a normalized 25 mm diameter and 100 mm length test sample of steel to be evaluated is heated uniformly to its austenitizing temperature. The specimen is then removed from the furnace and placed in the end quench test Apparatus and immediately end quenched by a jet of room temp. water.
