WebMedium and high hardenability steels are needed for gas quench, since the quenching power is lower compared to liquid quench 1 . The traditional Jominy end quench test and Grossmann test, ... WebHardenability is a measure of the ability to harden a steel to a given depth. It is not the same as hardness, which measures a material's ability to withstand penetration by a hard indenter. The factors that displace TTT curves to the right, inhibiting the transformation of austenite to pearlite, also increase the hardenability of the steel.

WebFor high hardenability steel, low gas quench HTC condition is needed to reveal its hardenability limitations. It is the fundamental limitations of Jominy test for gas quench that... Web1. Small cobalt additions (0.2–0.5%) have almost no effect on the kinetics of phase transformations, structure, or mechanical properties of steel 18Kh2N4MA, but lower its hardenability. 2. The addition of as much as 3% Co raises the change points and reduces the amount of retained austenite in the structure; cobalt strengthens the steel and lowers … flooring places in elmwood
