Graftech International Ltd

A maker of graphite electrodes—the giant carbon rods that recycle scrap steel in electric arc furnaces—plus the petroleum needle coke that feeds them, produced at its Seadrift, Texas plant. Its roots reach back to 1886, when Cleveland's National Carbon Company supplied the arc carbon that lit the world's first electric street lamps. Renamed GrafTech in 2002, it once won an Academy Award for the carbon used in cinema projectors.
