NEW YORK — Allegheny Technologies Inc.’s (ATI’s) 2003 lean duplex stainless alloy has been selected for topside secondary and outfitting structural components on a "major offshore project" in the North Sea, the company said.

The 2003 alloy was selected "to solve both corrosion and weight concerns," Pittsburgh-based ATI said.

"For years, 316L austenitic stainless and coated carbon steel have been used for these offshore applications. Recent reports have highlighted undesirable chloride pitting and corrosion cracking with 316L and significant maintenance costs with coated carbon steel in these marine environments," ATI chairman, president and chief executive officer Richard Harshman said.

The company couldn’t be reached for further details on the deal.
