Production process:

•After EF + LF + VD + ESR

•Smelting ensures YTG13R  has the quality of low gas content and high purity.

•The multi-directional forging (or forging opening + rolling) processing is adopted to make YTG13R  have 

•the characteristics ofsmall difference in anisotropy performance and high density.

•The advantages of YTG13R  are small banded, small grain size and uniform structure.

Steel properties

•It has excellent machining performance and workability.

•High thermal strength: good toughness, thermal fatigue and wear resistance at medium temperature.

•Heat treatment has small deformation and good hardenability.

Purpose:

•Precision zinc alloy die-casting mold, medium batch aluminum or magnesium alloy die-casting mold, 

semi-solid die-casting moldPure aluminum die casting mold

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

•Manufacturing of red forging die, hot extrusion die and flower bar

•Thermosetting plastic mold, lamp mold, glass mold

•The average life of e13r is better than that of h13esr die steel.
