34CrNiMo6 Alloy Steel round bar EN1.6582

34CrNiMo6 alloy steel is a high-strength nickel-chromium-molybdenum steel widely used for demanding engineering and industrial applications. Known for its excellent toughness, fatigue resistance, and superior hardenability, 34CrNiMo6 steel is ideal for components subjected to heavy loads, impact stress, and repeated mechanical pressure.

34CrNiMo6 steel bar is commonly supplied as round bar, forged bar, plate, and custom-machined components. Due to its excellent mechanical performance, 34CrNiMo6 alloy steel round bar is widely used in automotive, aerospace, mining, oil & gas, and heavy engineering industries.

Compared with conventional carbon steels, 34CrNiMo6 alloy steel provides improved tensile strength, deeper hardening capability, and better wear resistance. This makes 34CrNiMo6 steel round bar a preferred material for shafts, gears, crankshafts, and structural mechanical parts.
