* Delivery condition: as rolled.
Weldability:
It can be welded quite well without any precautions.
Hardenability:
Low hardenability; core quenching in water till a diameter of 12-15 mm; as far as bigger diameters are concerned, it hardens only till a certain depth, inversely proportional to diameter, like all non-alloy steels with medium-high carbon content.
