1.designing feature:high hardenability, high toughness
2.the process of smelting:EAF+LF+VD
1.Chemical Composition
Element | C | Si | Mn | Cr | Mo | V | P | S |
content | 0.38 | 1.00 | 0.40 | 5.10 | 1.40 | 0.50 | ≤0.003 | ≤0.005 |
2.Feature
*small heat deformation
*High hot strength and hardness
*Excellent corrosion resistance
*the tendency of the appearing of iron oxide skin are small in air-quenching
*good resistance to heat, good hot toughness, high resistance to temperature fatigue and wear in medium heat
*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.
3.Suggestion for Heat treatment
*temperature of anneal:860-890°C Hardness:≤229HBW
*temperature of quenching:1000-1030°C,oil or air cooling.
*temperature of tempering:530-580°C, double tempering. Tempering Hardness:47-49HRC
4.Application
the manufacturing of aluminum dies, hot extrusion dies, the perforation tool and the plastic mold.
the manufacturing of the 400-500°C temperature resistance construction parts for aircraft and rockets
