Abstract
The present disclosure provides rare earth die steel. Mg and B elements are added on the basis of adding rare earth element Y, so that the rare earth element purifies a matrix, and grain boundary occupation by Mg and B is fully utilized to regulate grain network chromium carbides. In addition, the B element can fully improve hardenability of austenite and ensure that non-martensite such as bainite does not appear during the cooling process, and therefore rare earth die steel with high impact toughness and high isotropy is obtained.
