Ferromanganese are alloys composed of iron and one or two more metals like Mn, Si, Ti, W etc. The ferro alloys have usually lower melting points than their respective alloying metals in pure stable form and thus, can be readily incorporated to obtain the metals as ferro alloys than in their pure terms starting from their ores. It is a principle alloying agent used in steel production steel/iron casting etc, where it also acts as a strengthener and deoxidiser. It imparts corrosion resistance to the products. Ferro manganese along with Fe-Si, Fe-Cr, is a bulk ferro-alloy, Manganese is also added in steels in the form of silico manganese. It dissolves in iron in all proportions, Iron for Farm implements uses upto 1.75% Mn and also in automobile parts. Ship construction industry uses steels with even higher content; riffle barrels and heat treated forgings necessarily use ferro manganese as an alloying additive.Ferro Alloys Plays major role in Steel Production and industrial development. Ferro-alloys are iron based alloys with varied elements introduced in steel making to cater to the specific needs. These are specified additions to the production of steel for various applications. Generally ferro-alloys are designated by base metal indicated as under such as: Ferro – silicon, Ferro – manganese, Silico – manganese, Ferro – chrome etc. Uses and Applications Ferro alloys are iron bearing alloys with additives which are passed on to steel to meet specific needs. The Ferro alloys are brittle and can be crushed to any size to be added to the molten steel as additives. Generally the additives as in steel are invariably added in the form of Ferro alloys. These are established additives in the steel production to obtain specific needs. Market Survey The demand for ferro alloys has been increasing with that of alloy and special steels. At the beginning of the previous decade, it was about half a million tonnes, increased to over 700,000 tonnes by 1997-98 and reached the level of 1.20 mn tonnes in 2006-07. There are six leading players and over 30 small producers. The industry has tied up with companies in Europe for technology inputs. The major users of alloy steel are: auto industry, railways, forgings, tubes, springs and other engineering industries.The leading players are Alloy Steel (SAIL), Mukand (Advanced Design Materials Corp., USA), Mahindra Ugine, Sunflag Irons & Steel, Vishveshvarya Steel, Kalyani Steel, Panchmahal, Indian Seamless, Shah Alloy Kalyani Carpenter.
