EN DIN 34CrNiMo6 | 1.6582 | 4337 Engineering Steel
Short description:
EN 34CrNiMo6 Steel is an important grade structural steel alloy in accordance with BS EN10083-3: 2006. 34CrNim06 steel has high strength, high toughness and good hardenability. steel EN / DIN 34CrNiMo6 has resistance to overheating ofresistance, but the white sensitivity of 34CrNiM06 ishigh. It also has temper brittleness, so the weldability of34CrNiMo6 material is poor. 34CrNiMo6 steel needs high-temperature preheating before welding in order to eliminate stressafter welding ...

Length: 3-5.8mm or customization
Surface: black, peeled, or rough chiseled
Heat treatment: air cooling, normalized, annealed, Q&T
Melting process: EAF + LF + V.D.

EN 34CrNiMo6 Steel

is an important structural steel grade according to BS EN
10083-3: 2006.34CrNim06 steel has high strength, high toughness and good

hardenability. Steel EN / DIN 34CrNiMo6 has stability
resistance to overheating, but the white sensitivity of 34CrNiM06 is
high. It also has temper brittleness, so weldability
34CrNiMo6 material leaves much to be desired. 34CrNiMo6 steel needs high
preheat temperature before welding to eliminate stress
after welding processing.

1.EN Steel 34CrNiMo6 Supply Range

Round steel bar Dimensions: 80mm diameter - 1200mm
Other steel shapes and sizes according to your requirements.

Surface: black, machined, peeled, turned or as per PECIAL requirements by other customers.

5.Heat Curing 34CrNiMo6 Structural Steel

Quenching and Tempering (Q + T) 34CrNiMo6 Steel

Heat 34CrNiMo6 round steel slowly up to 850 กใ C;

Soaking at this curing temperature, quenching in oil;

Temper as soon as 34CrNiMo6 steel to room temperature.

Heat evenly to a suitable temperature;

Take out from the oven and air-cooled.

The usual tempering temperature is 600 กใ C, which depends on the actual needs.

6.Forging according to DIN 34CrNiMo6 / 1.6582 steel

Hot forming temperature: 1100-900oC.

7.Machinability of steel 34CrNiMo6


best done with this alloy steel in annealed or normalized 1.6582

and released state. It can be processed by all conventional methods.



alloys can be fused or resistance welded. Preheating and after
heat welding procedures should be followed when welding this alloy with
established methods.


34CrNiMo6 steel is used for tool making, which requires good ductility and
high durability. It is usually chosen so as to make large sizes and important

parts such as heavy machinery axles, turbine shaft blades, high load
transmission parts, fasteners, crankshafts, gears, and to a large extent
loaded parts for engine construction, etc.
