SAE8620 Alloy Steel Bar Sae 8620 Steel Round Bar For Alloy Machining

Product Description

SAE8620 1.6523 Alloy steel for special alloy machining

8620 bar is a low alloy steel whose main components are iron (Fe), carbon (C), chromium (Cr), nickel (Ni) and molybdenum (Mo). Typical composition ranges are approximately 0.18-0.23% carbon, 0.70-0.90% manganese, 0.40-0.70% chromium, 0.40-0.70% nickel, and 0.15-0.25% molybdenum. These alloying elements help improve specific properties of the material, including its hardenability and case hardening characteristics

SAE 8620 bar has good forgeability and can be formed through processes such as heat treatment and mechanical processing. It can be easily forged, rolled, stretched and stamped into a variety of shapes and sizes.

Features:

SAE 8620 rod is ideal for applications requiring high surface hardness and wear resistance.

Good toughness and impact resistance

It has good machinability and is easy to perform machining operations such as turning, milling, drilling and grinding.
SAE 8620 rod has good weldability and can be welded using common welding techniques.

Has high yield strength, tensile strength and fatigue strength, and sufficient plasticity
and resilience;
SAE 8620 rods are corrosion-resistant steel, heat-resistant steel, and wear-resistant steel

Technical Parameters:

heat treatment
1) Preheat at 500-600℃ for 2-4 hours;
2) Insulation at 850-880℃ for 2 hours;
3) Oil cooling reaches 50-100℃;
4) After quenching, the hardness can reach 50-52HRC, and then tempered at 200℃,
The hardness can reach above 48HRC;

5.Smelting process
1) Electric furnace: electric furnace+LF+VD (optional);
2) ESR: electric furnace + LF + VD + electroslag remelting (optional);
