Allegheny Technologies Specialty Metals Certified by NORSOK, Norwegian Oil and Gas Industry Standard


PITTSBURGH, Pennsylvania - August 22, 2006 - Allegheny Technologies Incorporated announced today that ATI Allegheny Ludlum has received certification as a qualified producer under the NORSOK standards for certain flat-rolled products. The NORSOK standards are developed by the Norwegian petroleum industry and are intended to identify metals used in oil and gas applications that are safe and cost effective. The NORSOK audit was performed by Oystein Strandmyr of Statoil and Dr. Torfinn Havn of Aker Kvaerner.

"We are pleased to receive NORSOK qualification as the only US metals company with this prestigious quality certification," said Patrick Hassey, Chairman, President and Chief Executive Officer of Allegheny Technologies. "The qualification of our specialty metals for welded pipe and tube provide new opportunities for ATI, particularly in the rapidly growing offshore oil and gas market. Our lean duplex, duplex, and 6-moly superaustenitic stainless alloys provide options for customers to select the optimum alloy for the application."

AL2003(TM) lean duplex stainless, AL2205(TM) duplex stainless, and AL-6XN® superaustenitic stainless steel in strip and plate product forms received NORSOK qualification under Standard M-650 on August 3, 2006. ATI's titanium castings are also qualified under NORSOK Standard MDS T-02. ATI's proprietary AL2003 lean duplex stainless is an excellent substitution for Type 316L stainless steel, which has become more expensive due to high and volatile raw materials surcharges. AL 2003 stainless contains only about 3% nickel compared to approximately 10% nickel in Type 316L. In addition, AL 2003 stainless is stronger than 316L.
