ms and other special metals. The Company is one of the leading manufacturers of special steels, Superalloys and the only manufacturer of Titanium alloys in India.
MDNL is one of the few metallurgical plants of its kind in the world, designed to manufacture a wide range of special metals and alloys using integrated and highly flexible manufacturing systems. The Company manufactures unique combinations of metal and alloys. These special alloys have superior mechanical properties and better workability which are essential for special applications in aerospace, power generation, nuclear, defence and other general engineering industries. These products are key ingredients for strategic sectors in India, which typically cannot be imported from other countries due to its national security related concerns.
The manufacturing facilities include Primary and Secondary melting furnaces such as Electric Arc Furnace with Ladle Refining Furnace, Vacuum Degassing/ Vacuum Oxygen Decarburisation, Vacuum Induction Melting Furnace, Vacuum Induction Refining Furnace, Vacuum Arc ReMelting Furnace, Electro Slag Re-Melting Furnace and Electron Beam Melting Furnace. Subsequent operations are carried out at 6000T/1500T Forge Presses, Ring Rolling Mill, Hot Rolling and Cold Rolling Mills, Bar and Wire Drawing Mills etc. based on the output, form and sizes required. The auxiliary supporting services like conditioning, heat treatment, machining, pickling, quality control also forms part of MIDHANI's manufacturing processes.
The Company manufactures special steels like martensitic steel, ultra high strength steel, austenitic steel and precipitation hardening steel. It manufactures three varieties of Superalloys - nickel base, iron base and cobalt base. It also manufactures varieties of titanium alloys. Most of the orders executed by the Company are in the nature of an import substitute. The Company has the competence of developing and manufacturing customised alloys tailor-made to suit the specific requirements of customers for their critical applications. Presently, the company conducts the operations at manufacturing facility in Hyderabad. It is in the process of setting up two new manufacturing facilities in Rohtak and Nellore. It has several certifications including the ISO 9001:2008 - Quality Management System and AS 9100 C for manufacturing and supply of metals and alloy products. The Company has the research and development laboratory which is accredited to National Accreditation Board for Testing and Calibration Laboratories.
With the constant developments made over the years in various operational areas, by utilizing in-house research and development capabilities, the Company indigenized various critical technologies, alloys and products which reduced dependence on imports of these critical materials. The Company has been handling challenging developmental tasks, taking a lead position in indigenisation of critical technologies and products to render support to several programmes of national importance.
