Hot Work Tool Steel (DIN 1.2714/SKT4)
1. Smelting characteristic:
(1)high hardenability, high toughness, good ductility, high temperature performance.
(2)The use of Electric arc furnace (EBT)+ refining(LF)+ Vacuum(VD)make the production of die steel are in high purity and good performance
2. 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 resistanc
3. Application:
Used for making large size drop forging die and trimming die which is complex shape, impact loading large, operating temperature not high
4. MTC available
5. UT Test Passed
