The Effect of Cryogenic Treatment on W360 and E38K Hot Work Tool Steels
steel research international, Volume 95, Issue 9, September 2024.The cryogenic treatment facilitates the transformation of retained austenite to martensite to an undetectable limit, with about 3 times higher amount of the carbide precipitation for both steel types. Both steel types exhibit almost similar impact energy values at room temperature, but E38K steel has 2 times higher energy at 350 °C.
