1. Key Properties
X19CrNiMo4 is a high-strength, low-alloy steel that combines excellent toughness, wear resistance, and good weldability. This steel is alloyed with chromium, nickel, and molybdenum to enhance its hardenability and resistance to fatigue and wear. The round bar form allows for high-precision machining, making it ideal for applications that require both strength and dimensional accuracy. Its outstanding mechanical properties make it suitable for components that undergo high stress and wear in demanding industrial environments.
