PITTSBURGH — TMS International Corp. is promoting Raymond Kalouche to president and chief executive officer.

Kalouche will take the reins Jan. 1, succeeding Joseph Curtin, who has been acting president and chief executive officer of TMS, the parent company of Tube City IMS Corp., since 2009. Kalouche currently serves as chief operating officer of TMS as well as president and chief operating officer of the company’s mill services group.

Curtin, who has been chairman since 2011, will remain in a full-time position as executive chairman, leading the company’s board and executive management team.

Since 2007, he has spearheaded the growth of the company’s mill services segment into Europe, Latin America, South Africa and the Middle East.
