2\Main features
Smelting characteristics
1.The features of composition design:high hardenability, high toughness, good ductility, high temperature performance.
2.The use of  Electric arc furnace (EAF)+ refining(LF)+ Vacuum(VD)+ Vacuum Electro-slag (ESR)make the production of die steel are in high purity and good performance.
Suggesting for heat treatment
1.Anneal:860-890℃   Hardness:≤229HB
2.Temperature for Quenching:1020-1050℃,oil or air cooling.
3.Temperature for Tempering:560-580℃,Tempering Hardness:47-49HRC,using double tempering
4.Hardness:56~58HRC
NOTE: If use the gas nitriding or carburizing permeation can further strengthen the mold, but the nitriding temperature should not  higher than tempering temperature, in order to ensure that the intensity of center didn't reduced, enhance the mold life.
3\the performance advantages and the uses
(1)\Highlight advantage
*High hot strength and hardness
*good resistance to heat, good hot toughness, high resistance to temperature fatigue and wear in medium heat
*Small heat deformation
*The tendency of the appearing of iron oxide skin are small in air-quenching
*Excellent corrosion resistance
(2)\Application
Used in manufacture of  extrusion dies, the mandrel, the forging mold for die forging hammer, forging press dies and die insert for precision forging machine as well as aluminum, copper die-casting mold.
