* Delivery condition: soft annealed.

Weldability:
Due to the medium-high carbon content it can be welded with some precautions.
It is particularly sensitive to cracks in the heat altered zone.

Hardenability:
Steel grade with limited hardenability; if suitably treated in convenient sizes (till a thickness of 50-60 mm) it can give very good results.
