1. Key Properties
30CrNiMo8 (1.6580) is a high-strength, low-alloy steel known for its excellent combination of tensile strength, toughness, and fatigue resistance. This steel offers exceptional performance under high-stress conditions, making it an ideal material for demanding applications. The round bar form is particularly suited for components requiring precise dimensions, ease of machining, and high surface integrity. With good hardenability, this steel can be heat treated to improve its strength and wear resistance, ensuring reliability in both hardened and unhardened states.
