Production process:

The gas content of YTL8R is low and the purity is high after ef (electric furnace smelting) +

 LF (external refining) + VD (vacuum refining) or + ESR (electroslag remelting) smelting.

The YTL8R is characterized by compact structure, fine eutectic carbide and uniform

 distribution by multi-directional forging (or forging and rolling) and spheroidizing annealing.

Steel properties

Toughness is twice that of D2 (12% ledeburite series cold working die steel, with good anti collapse angle).

The machinability and abrasiveness are better than D2 (12% ledeburite series cold working die steel).

High wear resistance and excellent electrical machinability.

Heat treatment has small deformation and good hardenability.
