Dneprospetsstal uses advantages of up-to-date technologies, produces and sells high quality special steels and alloys, builds its business for the benefit of shareholders, partners and personnel.
Dneprospetsstal is the Ukrainian leader and one of the leading enterprises in the CIS working in special metallurgy. From the date of foundation in the year 1932 Dneprospetsstal Works has been specialising in manufacturing of stainless, tool, high-speed, bearing, alloyed constructional steel production as well as production of heat resistant nickel-based alloys. During this period producing of more than 800 steel grades and about 1000 sections of rolled stock has been developed.
Dneprospetsstal keeps mastering new products that are in demand in the market of special steels and alloys. Company activity aimed at the maximal satisfying of continuously increasing customer requirements, at setting up of long-lasting cooperation. Our long-term clients are our partners and we are proud that among them are not only world leading companies but also small firms. The number of buyers of our products is constantly growing. We are always pleased with new business contacts and open for partnership.

- cold-drawn bars with ground and polished surface from 2 to 50 mm in dia.
DNEPROSPETSSTAL constantly develops and modernizes production facilities, implementing new technologies and up-to-date equipment that results in the highest quality product performance .
The manufacturing process is an optimal combination of different technological procedures, which provide making high quality products with designed properties, meeting unique customer requirements.
Steel melting process is effected in four steel-making shops equipped with open-hearth basic electric arc furnaces with capacity 30 to 60 tones, one induction furnace from 8 tones and ESR-and VAR-furnaces.
Ingots applied are from 0,215 to 7,4 tones in weight. Steel can be cast in sheet slabs with weight 8,9 to 14,7 tones.
Steel –making shop № 1 is equipped with semi-continuos casting unite to produce consumable electrodes with square side of 370 mm for further electro slag remelting and round electrodes of 405 mm in dia for vacuum arc remelting.
In steel–making shop №2 argon-oxygen refining converter is installed which allows to produce low-carbon corrosion resistant stainless steel by duplex process- open electric arc furnace plus converter (EAF+AOD)
In the steel-making shop № 3 the high quality characteristics of steel are obtained by treatment of semi-product in DANIELI-ladle-furnace with further degassing of the melt in MANNESMANN DEMAG – degasser.
Steel–making shop №5 is equipped with ESR and VAR-furnaces of various capacities. Ingots for further working from 0,9 to 6,0 tones in weight and sheet slabs from 9,3 to 20,0 tones can be produced.
Steel products of high quality corresponding to strict requirements to metal structure and harmful impurities content can be manufactured by ESR-process.
The manufacture of bearing, structural and stainless steel, Ni-Fe Ni- based alloys and bimetallic ingots combining carbon and stainless steel by VAR- process is implemented. High quality steel products free of any non-metallic inclusions can be obtained by vacuum- arc remelting
In 1980 Powder metallurgy shop was put into operation, which allows producing tool and high-speed steels with unique characteristics. Steel making process is carried out in induction furnace with capacity 4 tones. Subsequent applying of cold and hot isostatic pressing at the temperature 1100-1150C? and at the pressure 1000atm. permits to obtain metal structure characterized by homogeneity shows no evidence of carbide basket in the shape of extrusions 500mm in dia and 1,8 in weight. The shop produces round forgings from 80 up to 350mm in dia, 1.5-5m in length.
Dneprospetsstal is specialized in manufacturing of different section rolled stock. Rolling of ingots 3,6-7,4 tones in weight for section mill and producing of rolled stock 1360-280 mm can be processed on «1050» roughing mill.
Round and square rolled stock of 8-130mm in section as well as flats, bars with parabolically shaped edges and trapezium section bars are produced according to intensive schemes/planes and optimal sizing on section mill “550”, “325”, “280” .
According to the program of the Company development, it is planned to put into operation a shop for metal finishing in the second quarter of 2002.
Two brand new Landgraf lines (Italy) for bar straightening, turning and grinding will be installed in this shop. So it will be possible to machine bars 17-200 mm in diameter with surface precision h 9. Cutting and packing equipment will work in the shop as well. Therefore product appearance and packing for transportation will be improved. New shop capacity is planned 4000 tones per month.
Dneprospetsstal pays close attention to constant product quality improving. This is one of main functions of each Company subdivision.
Our products are certified to ISO 9002 by TUV CERT Certification Body.
