5.Applications
34CrNiMo6 steel is often used in the manufacture of shaft under high load, such as connecting rod structure.DIN 1.6582 steel is also made the surface is hard wear-resisting and heart of flexible components, such as gear.It is also widely used in engine camshaft and connecting rod parts.

6.Forging
1)Preheat 1.6582 forged alloy steel carefully.
2)Raise the forging temperature up to 1150-1200°C.
3)Keep the forging temperature above 850°C.

7.Heat Treatment

Hardening&Tempering(quenched and tempered and after stress relieved)
1)Heating 34CrNiMo6 steel uniformly to 850°C;
2)W-Nr 1.6582 alloy steel should be quenched in the oil;
3)Heat the material to the temperature 550°C;
4)Soak at this temperature for at least 2 hours;
5)1.6582 alloy steel should be cooled in the furnace.

In case after QT a straightening process is necessary then the products should be tempered and distorsion-poor annealed with at least more than 625°C.

Annealing
1)Heating 1.6582 forged steel thoroughly to 800-850°C;
2)Cool slowly to the temperature 550°;
3)Complete annealing the steel in the air.

Normalizing
1)heat DIN 1.6582 steel until the temperature up to 850°C;
2)Then cool W-Nr 34CrNiMo6 steel down to the room temperature in the air.
