Allegheny Technologies, Inc. (ATI), shook up its executive ranks this week, naming three new division heads.

John Sims was named executive vice president of high-performance materials and components, Hunter Dalton was named executive vice president of strategic growth initiatives and Thomas Witheford will succeed Dalton as president of ATI Specialty Materials, part of the high-performance materials and components segment.

Sims and Dalton will continue to report to Richard Harshman, chairman, president and CEO.

“This is the next step in our strategy to reposition ATI as an aligned and integrated specialty materials and components business. Consolidating the leadership of ATI’s high-performance materials and components segment under John Sims will accelerate the alignment and integration of the separate business units that comprise this segment,” Harshman said.

Sims joined ATI in 1996 as a product metallurgist at ATI's continuous bar and rod mill operations in Richburg, South Carolina. Sims advanced through a variety of technical and operational responsibilities at ATI Specialty Materials, including being named vice president-operations for ATI Specialty materials in 2002.

Dalton joined ATI in 1981 as an industrial engineer for ATI Specialty Materials, and Witheford joined ATI in 1988 as a product engineer at ATI’s melt operations in Latrobe, Pennsylvania.
