Production process:

•After ef (electric furnace smelting) + LF (off furnace refining) + VD (vacuum refining) smelting, 

yt2353 has low gas content and good purity.

•The multi-directional forging (or forging opening + rolling) processing is adopted to make yt2353 have the characteristics of small difference in anisotropy performance and high density.

•After homogenization treatment and heat treatment process such as ultra refining + spheroidizing annealing, yt2353 has 

the characteristics of small band, fine grain size and uniform structure.

•The quality of yt2353 can meet the requirements of nadcas207 standard of Die Casting Association of North America.

•The production cost is reduced without ESR (electroslag remelting) and the cost performance is high.


Steel properties

·It has excellent machining performance and good polishing performance.

·It has better physical properties than H13 series, smaller thermal expansion coefficient and higher thermal conductivity.

·With H13 series better thermal fatigue resistance, fire resistance, erosion resistance and wear resistance.

·Heat treatment has small deformation and good hardenability.


Purpose:

Precision zinc alloy die casting die, aluminum alloy and magnesium alloy die casting die, semi-solid die casting die.

Small and medium batches of pure aluminum die casting mold

High temperature die casting mould for small batch of copper, liquid metal, etc

Manufacturing of red forging die, ploughing die and mandrel

Thermosetting plastic mold, lamp mold, glass mold

The service life of yt2353 is better than that of H13 series die steel.
