Products Description
34CrNiMo6 Steel is an important alloy engineering steel grade as per BS EN 10083-3:2006. 34CrNim06 steel has
high strength, high toughness and good hardenability. EN / DIN 34CrNiMo6 alloy steel has the stability of resistance to
overheating, but the white sensitivity of 34CrNiM06 is high. It also has the temper brittleness, so the weldability of
34CrNiMo6 material is poor. The steel 34CrNiMo6 needs the high temperature preheating before welding in order to
eliminate the stress after welding proces
Characteristics of DIN 34CrNiMo6 / 1.6582 Steel
34CrNiMo6 is a 1.8% nickel - chromium - molybdenum high hardenability high tensile steel - generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36).
Characterised by high strength and toughness in relatively large sections.
Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding.
34CrNiMo6 is used in most industry sectors for applications requiring higher tensile/yield strength than 4140 can provide.
High voltage bolts and nuts, crankshafts, cam shafts, transmission axles, torsion bars, drive shafts, pump shafts, worm shafts, conveyor rollers, stems, pins, tie rods, clutch discs. Large-mass dies for hot stamping. 34CrNiMo6 Steel is widely used in the aerospace industry for structural parts of flaps assembly, fuselage and landing gear, propeller plane axles.

Annealing: Heat to 800℃ – 850 ℃ , hold until temperature is uniform throughout the section and cool in furnace.
Flame or Induction Hardening: 1.6582 steel can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50. Parts should be heated as quickly as possible to the austenitic temperature range (830℃ – 860℃ ) and required case depth followed by an immediate oil or water quench, depending upon hardness required, workpiece size/shape and quenching arrangements. Following quenching to hand warm, most components should be tempered between 150℃ – 200℃ to remove quenching stresses in the case. This will have little effect on case hardness.
Hardening: Heat to 830℃ – 860℃, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.
*Temper immediately while still hand warm.
Nitriding: 1.6582 steel can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490℃– 530℃, followed by slow cooling (no quench) reducing the problem of distortion. Parts can therefore be machined to near final size, leaving a grinding allowance only. The tensile strength of the core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed. N.B. Nickel is inert to the action of nitrogen and in general resists its diffusion into steel. This can result in lower case hardness or longer nitriding cycle times for steels containing nickel such as 1.6582 steel.
Stress Relieving: Heat to 600℃– 650 ℃, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.
Tempering: Re-heat to 450℃– 660℃as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air. N.B. Tempering should be avoided if possible within the range 250℃ – 450℃ due to temper brittleness.
Notes on Heat Treatment: Heating temperatures, rate of heating, cooling and soaking times will vary due to factors such as work piece size/shape also furnace type employed, quenching medium and work piece transfer facilities etc.
