Properties of steel C40 (1.0511)
Weldability: Due to the medium-high carbon content it can be welded with some precautions. Hardenability: Low hardenability; it shows intermediate features between those of steels with medium and those of steels with high carbon content; therefore it is not easy to obtain the required features by quenching in oil and the quenching in water can result in cracking. |
