EN 10083-1 2C25 Introduce
The European Union (EU) has a history of enacting strict technical standards in order to ensure a high level of quality in goods and services produced by EU member states. EN 10083-1 2C25 is the result of this type of standards-making, originating in the late 1950s as the standardization of dimensions, tolerances, and processing of steel rolled on hot or cold-reducing mills. These mills roll hot or cold steel into various shapes and sizes, and the EN 10083-1 2C25 standard effectively outlined how to ensure a consistent and useful result.

EN 10083-1 2C25 Material Mechanical Properties
Fatigue is a measure of the material's ability to withstand cyclic loading without failure. EN 10083-1 2C25 steel has an excellent fatigue strength of 125-175 MPa at 1000 cycles which makes it suitable for use in components that are exposed to high frequency and vibration such as gears or shafts. The high fatigue strength can also provide longer life expectancy for these components.

EN 10083-1 2C25 Material Machining Technology
The first step in machining EN 10083-1 2C25 steel is selecting the most appropriate tool for the job. For most projects, a high-speed steel drill bit is recommended. This type of bit is designed to withstand the extreme heat and pressure generated during the machining process. However, if a greater degree of accuracy is required, other materials such as ceramics, cermets, or diamond-coated bits may be used.
