Product Description

DIN1.6523/SAE8620/20CrNiMo Alloy Steel Round Bar For Structure

1. Chemical Composition 

C	Si	Mn	Cr	Ni	Mo	S	P
0.18-0.23	0.15-0.35	0.70-0.90	0.40-0.60	0.40-0.70	0.15-0.25	≤0.035	≤0.035

2. 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 resistant steel, heat-resistant steel, wear-resistant steel, magnetic steel, and other
special physical and chemical properties of the steel;

3.Application:
1) Zinc, aluminum, magnesium and other  alloy die-casting molds;
2) Heat dies and all kinds of hot forged molds;
3) Metal extrusion die holder;

4. Ready Stock:
Round bar dia20-100mm black surface and hot rolled deliver condition.

5. Heat Treatment
1) Preheating 2-4 hours in  500-600°C;
2) Keeping temperature for 2 hours in  850-880°C;
3) Oil cooling to reach 50-100°C;
4) After quenching can reach a hardness of 50-52HRC, then tempered at 200°C,
then hardness can reach above 48 HRC;

6.Melting Process
