EN 10083-1 C55R Material Mechanical Properties

Yield strength is one of the most important mechanical properties of any material and EN 10083-1 C55Rsteel is no exception. It is the amount of stress required to cause a permanent deformation in the material. The higher the yield strength of a material, the harder it is to deform it and the better it is for use in critical structures. EN 10083-1 C55R steel has an excellent yield strength of 410-530 MPa which makes it suitable for use in highly stressed structures and components.

EN 10083-1 C55R Material Machining Technology

The last step in machining EN 10083-1 C55R steel is polishing or finishing the part. To achieve the smoothest surface possible, a deburring tool should be used. This removes any remaining burrs or rough edges, leaving the work piece with a smooth and professional finish. Additionally, polishing compounds can be used to give the steel a glossy, reflective finish.
