June 24 (Reuters) - U.S. Steel said on Tuesday Kevin

Lewis would replace CFO Jessica Graziano effective immediately,

days after the steelmaker closed its sale to Japan's Nippon

Steel ( NISTF ).

Graziano, who has spent nearly three years at the company,

would stay on as a special advisor until July 18 to aid with the

transition, U.S. Steel said.

Lewis who joined the Pittsburgh-based steelmaker 17 years

ago, has held key positions across finance, strategy and

investor relations.

The company also appointed Scot Duncan as senior vice

president, general counsel and secretary, effective immediately.

The move comes after Nippon Steel ( NISTF ) completed its

$14.9-billion acquisition of U.S. Steel last week, marking the

end to an 18-month regulatory battle.
