Widely Contruction Use Special Hot Rolled Polished SAE8620 Flat Bar Alloy Steel
20CrNiMo AISI, former U.S. Department of steel in SAE 8620 steel. Hardenability is similar to that of 20CrNi steel.
Although the Ni content in the steel is half 20CrNi steel, but due to the addition of a small amount of Mo element, the upper part of Austenite Isothermal Transformation Curve to the right; and because the appropriate increase of Mn content in the steel hardenability is still good, high strength than 20CrNi steel.
1) Demand has high yield strength, tensile strength and fatigue strength, there has enough plasticity
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;
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;
Round bar dia 20-100mm black surface and hot rolled deliver condition.
Full size flat bars
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;
1) EAF:Electric Furnace+LF+VD (Optional);
2) ESR:Electric Furnace+LF+VD+Eleroslag Remelted (Optional);
Packed with plastic film, seaworthing packing, others according to customers' requirements;
For abundant stock, 15-20 days.For customized products, 30-50 days.
All the sizes as require can be customerized as fresh production with MOQ,products of required specifications can be developed/produced per international, chinese or industry standards, or based on agreements with customers.
