The Role Manganese Plays in Stainless Steel
Manganese, the chemical symbol known as Mn and the atomic number as 25, is a grayishwhite, hardbrittle and shiny transition metal. Pure manganese is slightly softer than iron while impure manganese containing a small amount of impurities is firm and brittle; moist will oxidize the latter. Manganese abounds in nature. Soil contains % manganese.

Principles of Aluminothermic Welding Railtech UK
In 1893, experimentations on Aluminothermic reactions for the production of high purity Chromium and Manganese started. By the end of the 19th century this technology had been applied to the rail industry to weld two pieces of rail together. It is when all started.
