Thermal Center - Metallurgical Fundamentals of Heat Treating

Several test methods have been developed over the years to determine the hardenability of steel. Most of us have heard of the Jominy end-quench test (Fig. 2). Another is the S-A-C test, which is often applied to steel of low hardenability. The advantage of the S-A-C test lies in the fact that the three numbers give a good visual image of the Jominy End Quench Test for Hardenability of Steel Metallurgy(pipe) Understanding The Jominy End Quench Test(steel) HardenabilityTesting ParticularsUses of Hardenability ValuesEffects of Alloying and MicrostructureThe Jominy end-quench test measures the hardenability of steel; that 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 temper heat 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, martensite is hard, but brittle.

For example, the cooling rate at a distance of 10 mm (0.390 inch) from the quenched end is equivalent to the cooling rate at the center of an oil-quenched 28-mm (1.1-inch) diameter bar. Full transformation to martensite in the Jominy specimen at this position indicates that a 28-mm-diameter bar can be through-hardened (i.e., hSee more on industrialheatingAuthor James MarrowPublished Jul 16, 2019DoITPoMS - TLP Library The Jominy End Quench Test(steel) The Jominy end quench test is the standard method for measuring the hardenability of steels.
