Allegheny Technologies Inc. has selected a company to design, engineer and supply the USD 1.16 billion hot rolling mill it plans to install at its Brackenridge, Pennsylvania plant. Siemens VAI Metals Technology’s next-generation integrated hot rolling mill will be a critical part of ATI’s new advanced specialty metals hot-rolling and processing plant. The new facility will expand the plant’s product line, giving ATI the capability to add flat-rolled titanium and higher-strength nickel alloys, as well as a number of the alloys that ATI has focused on for growth potential and are being made at other plants. Groundbreaking is slated for later this year and the project is expected to be completed in about four years.
