Production process:

•After: ef (electric furnace ellipsometry)

 ＜ f (external refining) + VD (vacuum smelting) + ESR (inert gas protection electroslag remelting)

Smelting ensures that YTP80R has the quality of low gas content and high purity.

•The YTP80R processed by multi-directional forging (or forging plus and rolling)

 has the advantages of small anisotropy difference, uniform and dense structure.

•The hardness after aging hardening treatment is very uniform and the size is stable.

Steel properties

•It has excellent cutting performance and good flexibility in the pre hard state (37-43hrc) of higher hardware.

•It has excellent EDM performance and excellent corrosion performance.

•It is especially suitable for surface treatment processes such as nitriding, carbonitriding and surface coating.

•The pre hardening state is stable, even after deep processing, no stress removal is required.

Purpose:

•High precision plastic mold.

•High gloss appearance quality and transparent plastic mold.

•High quality etched bite plastic mold.

•Engineering plastic mold, rubber mold.
