DC53 Die Steel for Thread Rolling Dies - GeLiPu Special Steel

Thread rolling dies are tools used on thread rolling machines to roll threads through metal plastic deformation.

Generally, alloy steels Cr12MoV, SKD11, and DC53 are used. They are high-carbon high-chromium steels with high hardenability and tempering stability, which also improve impact toughness and refine grain size. The carbides in these steels are complex chromium-iron carbides. The high chromium content causes uneven carbide distribution, often in banded or network patterns. Additionally, the undercooled austenite of this steel is very stable, and after quenching, a large amount of retained austenite ensures minimal volume deformation. Therefore, such steels are used to make thread rolling dies.
