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

Good machinability in the annealed condition and good aptitude / endurance  to heat treatment; this steel grade undergoes heat treatment without important deformations.

Hardenability:
It has a low-medium hardenability enabling the use, with good core resistance, till a thickness of about 50 mm.
