What is C45 steel?

What is C45 steel?

C45 grade steel is a medium carbon steel offering moderate tensile strengths. The material is capable of through hardening by quenching and tempering on limited sections but can also be flame or induction hardened to Hrc 55.

Is C45 alloy steel?

The standard ISO 683-1:2018 supersedes BS EN 10083-2:2006 which also specifies C45. It is a British standard adopted from ISO which specifies heat-treatable steels, alloy steels and free-cutting steels and Non-alloy steels for quenching and tempering. The standard supersedes BS EN 10083-2:2006 which also specifies C45.

Is C45 low carbon steel?

C45 grade steel is a medium carbon steel offering moderate tensile strengths. Machinability similar to that of mild steel can be expected, however weldability is reduced.

What is the chemical composition of C45?


Element C Cr
Min. 0,42
Max. 0,50 0,40

Does C45 steel rust?

The paper presents the results of research, concerning the increase of corrosion resistance of C45 carbon steel after the processes of mechanical surface finishing. It was found that the corrosion rate may be decreased several times without using any corrosion inhibitor or protective coating.

Is 4140 a carbon steel?

Carbon Steel (by definition) Simply put, carbon steel by definition is extremely simple. It’s Iron with some carbon, and limited alloying elements. In addition, any steel that requires alloying elements (like 4140 and 4340, for example) are not carbon steels.

How hard is C45 steel?

Which is better JIS s45c or DIN C45?

It also can be called JIS S45C and DIN C45 steel. It is usually used in normalized condition because of its bad hardenability. It needs to be quenching and tempering treatment to get higher mechanical performance.

What are the properties of steel C45 1.0503?

Properties of steel C45 (1.0503) Weldability: Due to the medium-high carbon content it can be welded with some precautions. Hardenability: It has a low hardenability in water or oil; fit for surface hardening that gives this steel grade a high hardness of the hardened shell. Equivalent grades of steel C45 (1.0503) Warning!
