EN 10083-1 1.1151 Introduce
The tensile strength test measures the maximum force in a pull test, while the impact test measures how the characteristics of the alloy change under stress. The metallographic test maps the surface and inner structure of the steel, allowing for the surface imperfections to be evaluated and the mechanical strength to be evaluated. Tests like these provide a comprehensive assessment of the strength, usefulness, and safety of EN 10083-1 1.1151 steels, and are carried out along each step of the production process.

EN 10083-1 1.1151 Material Mechanical Properties
Fatigue is a measure of the material's ability to withstand cyclic loading without failure. EN 10083-1 1.1151 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 1.1151 Material Machining Technology
The last step in machining EN 10083-1 1.1151 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.
