PITTSBURGH -- ATI Allvac, an Allegheny Technologies Incorporated (NYSE:ATI) company, earlier this week commissioned its recently expanded Richburg, SC high performance metals long products rolling facility. The expansion significantly enlarges the facility's operating capacity and increases value-added process capabilities including coil processing.

Significant growth potential exists in many markets including aerospace, oil and gas, power generation, transportation, corrosion and biomedical." Speaking to the Richburg plant's employees, customers and suppliers, Mr. Hassey said, "I challenge you to stay connected, to execute flawlessly and to realize the full potential of this new facility. I look forward to watching you serve the global markets from Richburg."

The expansion increases the number of services ATI Allvac offers on products such as nickel-base superalloys, titanium and titanium-base alloys and premium specialty steels. The enhanced rolling mill is engineered to improve product quality and reduce product cycle times in order to meet the changing requirements of ATI Allvac's customers and global markets.
