High Manganese Steel Essay
The properties are mainly controlled by the chemical composition of the steel. In high manganese steels, manganese is the major alloying element, accounting for a larger weight percentage. Manganese contents are considerably higher than those found in common steel grades (Hills et al., 2015). Regarding the major alloying elements in high manganese steels, Table 1 gives the approximate range of contents currently being studied.

Integrated steel plants make different grades of steels based on the steel chemistry, which also includes low alloy steels. Most of the alloy additions are carried out in the secondary steelmaking process. Recently steelmakers are attracted towards high manganese steels due to its potential material properties in the automobile manufacturing sector.
Secondary steelmaking process
Secondary steelmaking has become an integral feature of modern steel plants. All the different processes applied to liquid steel after the initial steelmaking process, prior to the continuous casting process, are included in the secondary steelmaking process. The tolerance levels of interstitial impurities and inclusions are lower in continuous casting than within ingot casting, and this has made secondary refining a critical component in order to control the impurities found in liquid
