Mechanical property test of thin steel plate


Tensile test shall be conducted for thin steel plate products to check its strength limit, tensile strength, yield point elongation, total elongation under maximum force and elongation at break. In addition, the steel sheet is usually tested to determine its tensile strain hardening index (n-value) and plastic strain ratio (n-value) in one or more areas of the tensile stress-strain curve.



detailed information



Sheet steel has a wide range of applications, such as automobiles, household appliances, electronic transformers, food packaging and construction. Compared with earlier products, today's sheet steel has made great progress. Its mechanical properties, surface processing, size and other quality characteristics can provide better control. It can meet the increasing demand for high performance end applications. In order to meet the needs of different users, people make steel sheets have specific properties; The thickness of thin steel plate is generally about 0.2mm to 6mm;

Tensile test shall be conducted for thin steel plate products to check its strength limit, tensile strength, yield point elongation, total elongation under maximum force and elongation at break. In addition, the steel sheet is usually tested to determine its tensile strain hardening index (n-value) and plastic strain ratio (n-value) in one or more areas of the tensile stress-strain curve. Steel sheet production requires high test processing capacity and very stable test results. The test equipment must be easy to use and highly repeatable. The test control software should not only maintain accurate control to obtain stable test speed, but also use advanced algorithms to calculate the test results of various stress/strain curves.


Solution


Full series of closed-loop control testing machine and automatic tensile testing system. The testing machine can support various loads, such as the maximum load of the bench type testing machine is 50 kN, while the load of the floor type testing machine is 50 kN to 3000 kN. All systems can realize accurate measurement of wide load, which means that various products can be tested without replacing load sensors. These dimensional data are automatically transferred to the software. These automation systems reduce the variability of operator measurement technology and improve the reliability and repeatability of test results.
