Manganese - Wikipedia
Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide.
Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.,
The Properties and Effects of Manganese as an Alloying Element
Manganese has similar effects like carbon, and steel producers use both of these elements to achieve a material with preferred properties. Manganese is required for the hot rolling process of steel by combining it with sulfur and oxygen. Steels often include 0.30% manganese, but certain carbon steels can include up to 1.5% of manganese.
Metallurgy Matters: Carbon content, steel classifications,
Aug 28, 2003· Steel classification is important in understanding what types are used in certain applications and which are used for others. For example, most commercial steels are classified into one of three groups: plain carbon, low-alloy, and high-alloy. Steel classification systems are set up and updated frequently for this type of information.
Manganese - Element information, properties and uses,
By far, the most important one is in steel making. When Sir Henry Bessemer invented the process of steel making in 1856, his steel broke up when hot rolled or forged; the problem was solved later that year, when Robert Foster Mushet, another Englishman, discovered that adding small amounts of manganese to the molten iron solves the problem.

SAE/AISI Carbon Steel Naming Conventions
The non-resulfurized high-manganese carbon steels are developed for ensuring better machinability. The second digit of the series indicates the presence of major elements, which may affect the properties of the steel. For example in 1018 steel, the zero in the 10XX series depicts that major secondary elements such as sulfur, are not present.
