Applications of 34CrAlNi7 round bar, hot-rolled, quenched, tempered and stress-relieved

34CrAlNi7 steel in hot-rolled round bars, quenched, tempered and stress-relieved, represents an advanced solution for components intended for nitriding. The combined presence of chromium, aluminium and nickel guarantees an excellent response to the surface treatment.

This material is ideally used in the production of precision gears, camshafts and components requiring high surface wear resistance while maintaining good core toughness. Stress relieving ensures maximum dimensional stability during nitriding.

The structure obtained after quenching and tempering and stress relieving guarantees uniform mechanical properties and an excellent response to the nitriding treatment.
