The Jominy test provides a measure of the hardenability of the steel. A standardised bar, 25.4 mm diameter and 102 mm long, is heated to the austenitising temperature and then placed on a rig in which one end of the rod is quenched by a standard jet of water. This results in a progressive decrease iRead more
The Jominy test provides a measure of the hardenability of the steel.
See lessA standardised bar, 25.4 mm diameter and 102 mm long, is heated to the austenitising temperature and then placed on a rig in which one end of the rod is quenched by a standard jet of water.
This results in a progressive decrease in the rate of cooling along the bar from the quenched end. The depth from the quenched end, over which martensite is obtained, is then the measure of hardenability.
