Conversion

Are you looking for additional mill processing capacity on either a short- or long-term basis? Do you need a reliable source that will not only provide conversion services for your alloys, but has the expertise and capabilities that many other mills lack?

Special Metals Corporation, the world's largest and most-diversified producer of high-performance nickel-based alloys, is now offering its resources, expertise, and excess capacity to other metals producers for toll work. This service is available through our manufacturing facilities in Huntington, West Virginia; Dunkirk, New York; New Hartford, New York; Burnaugh, Kentucky; Elkhart, Indiana and Hereford, England.

Special Metals produces nickel alloys in all significant mill forms from large ingots and billets to flat stock, seamless tubing, bar and wire, the latter of which includes core and filler wires for welding products. Its specialty metals are used in some of the world's most technically demanding industries and applications, including: aerospace, power generation, chemical processing, and oil exploration.

While Special Metals production facilities are ideally suited for nickel-based alloys, we are capable of processing a wide range of ferrous and non-ferrous alloys through the same facilities. Operations of the Company's production facilities include the melting, remelting, forging, hot rolling and finishing of rod, sheet/strip, plate, tubular products, extrusion, large diameter tube reduction, mechanically-alloyed powder manufacture, and by cold strip finishing.
