*  Delivery condition: subjected to a softening treatment according to the maximum hardness prescription.

Weldability:
It is a MnCr alloy steel, easily hot machinable and weldable.

Hardenability:
It has a low hardenability and therefore it can show good core features till thicknesses of about 20 mm.
