34CrNiMo6 (DIN 1.6582, EN 10083-3) is a premium high-hardenability alloy steel bar featuring nickel-chromium-molybdenum composition. This hot-rolled steel bar is supplied hardened and tempered in the tensile range of 930-1080 MPa, delivering exceptional strength and toughness even in large sections.
Diameter Range: 10-350mm
Length: Custom cut to your requirements
Condition: Hardened and tempered (Condition U)
34CrNiMo6 is characterized by high tensile strength and superior toughness in relatively large cross-sections. The pre-hardened and tempered material can be further surface hardened through flame or induction hardening processes, as well as nitriding treatments.

Heat to 800°C - 850°C, hold until uniform temperature throughout section, and cool in furnace.
34CrNiMo6 hardened and tempered bar can achieve case hardness exceeding Rc 50. Heat rapidly to 830°C - 860°C austenitic range, then quench in oil or water. Temper between 150°C - 200°C to remove quenching stresses.
Heat to 830°C - 860°C, maintain uniform temperature, soak for 10-15 minutes per 25mm section, then quench in oil, water, or polymer. Temper immediately while hand warm.
Achieves surface hardness up to Rc 60. Process at 490°C - 530°C with slow cooling. Nickel content may require longer nitriding cycles due to resistance to nitrogen diffusion.
Heat to 600°C - 650°C, maintain uniform temperature, soak for 1 hour per 25mm section, and cool in still air.
Re-heat to 450°C - 660°C as required, maintain uniform temperature, soak for 1 hour per 25mm section, and cool in still air. Avoid tempering between 250°C - 450°C due to temper brittleness.
