Hardenability Testing.As stated above,different chemical composition has an effect on hardenability.In order to quantify the differences in hardenability,engineers developed a standard reference test for hardenability,the Jominy end quench test per ASTM A255.This test provides data for the changes in hardness along the length of a 1 diameter x 4 long round test bar.Understanding the Jominy End-Quench Test 2015-05-07 HardenabilityTesting ParticularsUses of Hardenability ValuesEffects of Alloying and MicrostructureHardenability is the ability of the steel to partially or to completely transform from austenite to some fraction of martensite at a given depth below the surface when cooled under a given condition from high temperature.A quench-and-temperheat treatment uses this phase transformation to harden steels.Tempering the martensite microstructure imparts a good combination of strength and toughness to the steel.Without tempering,martensitSee more on industrialheatingAuthor James MarrowPeople also askWhat is The Jominy end up test?What is The Jominy end up test?The Jominy end-quench test is the standard method for measuring the hardenability of steels.This describes the ability of the steel to be hardened in depth by quenching.Hardenability depends on the chemical composition of the steel and can also be affected by prior processing conditions,Understanding the Jominy End-Quench Test 2015-05-07 The Jominy end quench test - idc-onlineThe Jominy end quench test Introduction The Jominy end quench test is used to measure the hardenability of a steel,which is a measure of the capacity of the steel to harden in depth under a given set of conditions.This TLP considers the basic concepts of hardenability and the Jominy test.

3.1 This test method covers the procedure for determining the hardenability of steel by the end-quench or Jominy test.The test consists of water quenching one end of a cylindrical test specimen 1.0 in.in diameter and measuring the hardening response as a function of the distance from the quenched end.35.4 Uses of Jominy Data - Engineering LibreTextsAug 25,2020 Jominy End#0183;For example,the cooling rate at a distance of 9.8 mm from the quenched end is equivalent to the cooling rate at the centre of an oil-quenched bar with a diameter of 28 mm.Full transformation to martensite in the Jominy specimen at this position indicates that a 28 mm diameter bar can be through hardened,i.e.hardened through its full thickness.35.3 Jominy Test - Engineering LibreTextsAug 25,2020 Jominy End#0183;Video clip 3 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).Jominy test specimen.The steel sample is normalised to eliminate differences in microstructure due to previous forging,and then austenitised.This is usually at a temperature of 800 to 900 Jominy End#176;C.
