EN 10083-1 1.6580 Material Mechanical Properties
Fatigue is a measure of the material's ability to withstand cyclic loading without failure. EN 10083-1 1.6580 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 1.6580 Material Machining Technology
The first step in machining EN 10083-1 1.6580 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.
