DIN 34CrNiMo6 4337 QT Hot Rolled Steel Bar

DIN 34CrNiMo6 4337 QT Hot Rolled Steel Bar

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.

13: 34CrNiMo6 Steel 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.

14: 34CrNiMo6 Steel Application

34CrNiMo6 are used for  heavy machinery axle,turbine shaft blade, high load of transmission parts, fasteners, crank shafts, gears, as well as heavily loaded parts for motor construction etc.

15: Delivery Condition
