Mceg 3442 mechanical laboratory – i experiment: jominy hardenability – version 1 general test instructions: normalize an astm-standard jominy specimen and perform a jominy end quench test on an sae steel specimen. The jominy end quench test astm a 255 measures hardenability of steels hardenability is a measure of the capacity of a steel to be hardened in depth when quenched from its austenitizing temperature.
Abstract the jominy end quench test is useful in determining the hardenability of a material a sample, such as 4140 steel which is used in this experiment, is transformed entirely into a single solid phase. Hardenability the jominy end quench test measures the hardenability of steel this is the ability of the steel to partially or to completely transform from austenite to some fraction of. The jominy end quench test is a standardized test (astm a255) used to determine the hardenability of a steel specimen if austenitizing of steel is performed correctly, the transformation to the hard martensite phase is controlled mainly by carbon and alloy content along with quench rate.
