The Jominy end quench test is the standard method to measure the hardenability of steels [1]. fThe Jominy End Quench Test The test sample is a cylinder with a length of 102 mm (4 inches) and a diameter of 25.4 mm (1 inch). The steel sample is normalised (to eliminate differences in microstructure due to previous forging) and then austenitised. ASTM A255 Standard Test Methods for Determining the The full name of the standard is as follows:ASTM A255 Standard test methods for determining the hardenability of steel. 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.

ASTM-A255 Standard Test Methods for Determining

1.1 These test methods cover the identification and description of test methods for determining the hardenability of steels. The two test methods include the quantitative end-quench or Jominy Test and a method for calculating the hardenability of steel from the chemical composition based on the original work by M. A. Grossman. Factors That Affect Hardenability Gear Solutions Feb 17, 2017 · The ideal diameter is a true measure of hardenability associated with a steel composition. The concept of the ideal diameter can be used to determine the critical size of steels quenched in quenchants of differing severity. The calculation of the ideal diameter, DI, for non-boron containing steels relies on a series of multiplying factors.
