1.Feature:
1) Demand has high yield strength, tensile strength and fatigue strength, there has enough plasticity
and toughness;
2) Demanding by refining outside the furnace, vacuum electroslag remelting or processing, or double vacuum smelting, vacuum induction furnace smelting suitable heat treatment;
3) Corrosion rElectromagnetic Equipment esistant steel, heat-resistant steel, wear-resistant steel, magnetic steel, and other
special physical and chemical properties of the steel;2.Application:
1) Zinc, aluminum, magnesium and otheralloy die-casting molds;
2) Heat dies and all kinds of hot forged molds;
3) metal extrusion die holder;3. Ready Stock:
Round bar dia20-100mm black surface and hot rolled deliver condition.4.Heat Treatment
1) Preheating 2-4 hours in500-600°C;
2) Keeping temperature for 2hours in850-880°C;
