Product Description

 

DIN 34CrNiMo6 / 1.6582 | ASTM 4337 Engineering Steel

Quick Details

1: 34CrNiMo6 steel introduction
    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 processing.

4: 34CrNiMo6 steel mechanical properties  

  The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat Treatment
Quenched and Tempered (Q+T) of 34CrNiMo6 Steel
    Heat 34CrNiMo6 round steel slowly to the temperature of 850°C;
    Soak at this hardening temperature quench in oil;
    Temper as soon as 34CrNiMo6 steels reach room temperature.
    Heat uniformly to the suitable temperature;
    Withdraw from the furnace and cool in the air.
    The usual tempering temperature is 600°C which depending on the actual requirements.

Forging 
    Hot forming temperature: 1100-900oC.
Machinability
    Machining is best done with this 1.6582 alloy steel in the annealed or normalized and tempered condition. It can be machined by all conventional methods.
Welding
    The alloy materials can be fusion or resistance welded. Preheat and post heat weld procedures should be followed when welding this alloy by established methods.

 

7: Delivery condition
    For hot forged bar, usually the delivery condition is hot forged, annealed/QT rough turned/Black surface.
    For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
    For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
    For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
