Microstructure and Mechanical Properties of High

In recent years, the leading scientific centres focus their research on improvement of mechanical properties of steels used for car manufacturing. These steels belong to a so-called 2nd generation of steels showing above-the-average plasticity while maintaining high strength. Thanks to these properties, they may be used successfully in automotive, armaments or railway industries for elements

About Manganese International Manganese Institute

Manganese it´s an essential component of steel-making process because it improves certain properties that steel by itself doesn´t have. To name a few, manganese allows to avoid a phenomenon called “hot shortness”, which causes a surface cracking process at high temperatures, it has an important ability to combine with Sulphur (an unwanted element in steel), and it has a powerful
