3. Features
A, Electroslag remelting steel, the steel has a high hardenability and resistance to thermal cracking.
B, Contains higher levels of carbon and vanadium, good wear resistance, toughness is relatively weakened, with good heat resistance.
C, Good strength and hardness at higher temperatures, high wear resistance and toughness, excellent overall mechanical properties and high resistance to tempering stability.

4.  Applications
For the manufacture of large impact load forging die, hot extrusion die, precision forging die; aluminum, copper and its alloy die-casting mold.
A, Die die, such as: mold kernel, inserts, thimble, sleeve.
B, Extrusion die, such as: mold, mold pad, bushing.
C, Aluminum and copper hot pressing molding die.
D, Cold, trimming, hot shear, tightening ring and wear parts.
