PD613 die steel features excellent wear resistance and durability up to a high mirror degree (around #10000), excellent flower etching processing. Heat treatment has small size change and excellent toughness. Chemical composition of PD613 die steel (SKD11 modified type) C carbon 0.03Si Silicon 0.10 Mn Mn 1.00S sulfur 0.03P phosphorus 0.030Cr chromium 0.35 Ni nickel 0.40 Cu copper 0.50~1.50 PD613 Die steel Application Datong plastic die steel PD613, It has excellent hardness, wear resistance and mirror-like properties, and good toughness and life. In addition, PD613, heat treatment is not easy to deformation, good processing.

Die steel for plastic moulds with wear resistance equivalent to SKD11. The hardness after heat treatment is approximately 56 to 61 HRC and has excellent wear resistance.

Compared with SKD11, the primary carbide distribution is better and the particle size is smaller, so the mirror and grain properties are improved.
