Metallurgical Effects of Manganese on Steels. Manganese is present in all steels as a de-oxidizer. Manganese reduces the tendency towards hot-shortness or popularly known as red-shortness resulting from the presence of sulphur, which enables the metal to be hot-worked. When manganese is absent or very low, the predominant sulphide in iron ...

Abstract A large amount of manganese has been added to next-generation advanced high strength steels for automotive applications. The increased manganese content changes the microstructural and mechanical characteristics by varying both the stacking fault energy and the austenite stability, but it is known to deteriorate weldability. …
High manganese steel typically contains around 11% to 15% manganese, which is significantly higher than traditional steel. The high manganese content creates austenitic crystals during solidification, resulting in work-hardening ability – a unique characteristic of this material. Additionally, the presence of carbon further enhances the ...
