Characteristics and Uses

GRADE TOOL STEEL CHARACTERISTICS MAIN APPLICATIONS
Hot Works DAC-10 Excellent heat crack and wear resistance at elevated temperature. Steel for precision die casting and hot press die.
DAC-3 Hot work tool steel with higher toughness than DAC. For Al extrusion dies with high hardness or hot forging press dies with good crack resistance.
DAC Standard grade with good balance of toughness, strength at elevated temperature and with excellent hardenability. For general use.
YXR-33 Matrix-type high speed steel with high toughness. Excellent strength and wear resistance at elevated temperature and excellent erosion resistance. Steel for warm and hot precision forging dies and insert pins for die casting.
Cold Works    SLD Cold work die steel with high abrasion resistance for general use, excellent harden-ability and minimal quench stress.  Cold work dies for general use, forming roll, shear blade 
SGT  Cold work die steel with superior machinability for general use; Special care is required for quenching large-size dies or wire electric discharge machining.  Dies for deep drawing, gauges. 
 SLD-MAGIC High-performance cold work tool steel attaining both extended die life and easy die fabrication.  Cold work dies for high-tensile steels, SUS, mass production, and general use. 
 SLD10 Extreamly high hardness with excellent toughness in die steels.  Rolling dies. 
Plastic Molds    HI-PM38 Flame retardant resin.  Transparent parts, Rubber 
 HI-PM31  Wear resistant Mold for engineering resin(Gear, Connector, IC)
 CENA1 Rust resistant  mold with sensitive surface as mirror polishing, creping, EDM, Weldless Mold 
High Speed   YXM1 High speed steel with high abrasion resistance and toughness for general use.  Cold forging dies, cold heading dies, slitter.
