Sep 29, 2014· Effects of Mn content in steel. Mn improves hot workability by preventing the formation of low melting iron sulfide (FeS). Steels with a Mn/S ratio of at least 8/1 do not exhibit hot shortness. Manganese sulphide (MnS), which forms preferentially to FeS, has a high melting point and appears as discrete and randomly distributed globules.
The impacts associated with manganese losses are evaluated at each stage of production by calculating the cumulative impact on supply chain costs, consumables and emissions. In each case, the costs of manganese losses are captured by considering the impacts associated with a 1% increase in the recovery rate of each stage of production.
