Product Desciption
1.6523/SAE8620/20CrNiMo Special Steel Alloy Steel Round Bar For Gear Wheels
Product Introduction
8620 steel bar is a low carbon nickel chromium molybdenum alloy with good carburized properties, formability, and weldability. This grade is a low-cost steel that is the most widely used carburizing alloy. Due to its nickel content, this grade has a high strength case and core toughness. The chromium and molybdenum support carburizing, and give good surface hardness and wear.
