 6.Characteristic of 1.2344 alloy steel: 

 1)high hardenability, high toughness, good ductility, high temperature performance

   the use of Electric arc furnace(EBT)+refining(lf)+Vacuum  (CD) make the production of die steel are in high purity and   good performance

2)high hot strength and hardness

   good resistence 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

3)Hot-work steel with good high temperature strength and high wear resistance.
