AISI/SAE 8620 Carbon Steel Bar Description
8620 alloy steel is a medium-carbon low-alloy steel with high hardness and dimensional stability, as well as high strength and plasticity. In addition, 8620 alloy steel also has good weldability, forgeability and processability, and is widely used in industrial fields such as manufacturing shaft parts, gears, carburized parts, crankshafts and machine tools. 8620 alloy steel is widely used in aviation, automobiles, machinery and other fields, especially in manufacturing high-load, high-strength and fatigue-resistant parts.
