1. Key Properties
30CrNiMoV9 is a high-performance, low-alloy steel designed to provide an excellent balance of strength, toughness, and hardenability. This steel grade is alloyed with chromium, nickel, molybdenum, and vanadium, which enhances its mechanical properties, including high tensile strength, wear resistance, and fatigue strength. It exhibits superior hardenability and toughness, making it ideal for components that are subject to high-stress, dynamic loads, and require resistance to fatigue. The round bar form offers ease of machining, ensuring precise components that are suitable for a wide range of industrial applications.
