Production process:

•After EF + LF + VD + ESR

•The smelting ensures that YTG23R   has the quality of low gas content and high purity.

•Adopt large forging ratio and multi-directional forging with forging ratio ≥ 

8 (large forging ratio of N8 into bloom + rolling) for processing

•YTG23R  has the characteristics of smaller difference in anisotropy and higher density.

•After homogenization (48 hours) and heat treatment processes such as ultra refining + spheroidizing

 annealing YTG23R  has the advantages of small band, small grain size and very uniform structure.


Steel properties

•It has excellent machining performance and polishing performance.

•Excellent thermal strength: high temperature toughness, thermal fatigue resistance, 

fire resistance and impact resistance

•The properties and wear resistance are better than those of 8407 and 1.2344.

Heat treatment has small deformation and good hardenability.


Purpose:

• precision zinc alloy die casting die, mass aluminum alloy and magnesium alloy die casting, especially for 

high-precision die casting dieand large-scale die casting die manufacturing.

High temperature die casting mould of pure aluminum, steel, liquid metal, etc.

Manufacturing of precision red forging die, long life MF die and mandrel.

• thermosetting plastic mold, lamp mold, glass mold.

The service life of ytg23r is better than 8407 and 1.2344 steel.
