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
