In order to improve its machinability, this steel grade can be supplied upon request with Pb (lead) addition, for example Pb=0,15%÷0,35% Weldability :Due to the medium-high carbon content it can be welded with some precautions. C40 - BEBON steelC40 steel plate, EN 10083 C40 steel plate, under EN 10083 standard, we can regard C40 steel plate as high carbon steel.. C40 steel plate is one mainly of high carbon steel,EN 10083 C40 steel plate is meduim Carbon Steels are similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% & the manganese from 0.50 to 1.65%. Increasing the carbon content is approximately 0.5% with C40 / 1.0511 - SteelNumber - Chemical composition Brinell hardness (HBW):(+SH) 163 - 211. 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
C40 Carbon Steel is a common medium carbon and medium tensile steel, with improved strength over mild steel, through-hardening medium carbon steel. C40 Carbon Steel Round Bar is also readily machinable in any condition. C40 steels are generally used in the as supplied untreated condition.

Non-alloy quality steel, for heat treating, suitable for mechanical applications.
EN 1.0503 Material C45 Steel. EN 10083-2 C45 steel (EN 1.0503) is a high strength medium carbon quality steel.
